Chinnmastaka or Chhinnamasta (Sanskrit: छिन्नमस्ता, Chinnamastā,
 "She whose head is severed"), often spelled Chinnamasta and also called
 Chhinnamastaka and Prachanda Chandika, is one of the Mahavidyas, ten 
Tantric goddesses and a ferocious aspect of Devi, the Hindu Divine 
Mother. Chhinnamasta can be easily identified by her fearsome 
iconography. The self-decapitated goddess holds her own severed head in 
one hand, a scimitar in another. Three jets of blood spurt out of her 
bleeding neck and are drunk by her severed head and two attendants. 
Chhinnamasta is usually depicted standing on a copulating couple.
Chhinnamasta is associated with the concept of self-sacrifice as well as
 the awakening of the kundalini – spiritual energy. She is considered 
both as a symbol of self-control on sexual desire as well as an 
embodiment of sexual energy, depending upon interpretation. She 
symbolizes both aspects of Devi: a life-giver and a life-taker. Her 
legends emphasize her sacrifice – sometimes with a maternal element, her
 sexual dominance and her self-destructive fury. Though she enjoys 
patronage as part of the Mahavidyas, her individual temples – mostly 
found in Northern India and Nepal – and individual public worship is 
rare, due to her ferocious nature and her reputation of being dangerous 
to approach and worship. Her individual worship is restricted to heroic,
 Tantric worship by Tantrikas, yogis and world renouncers.
Chhinnamasta is recognized by both Hindus and Buddhists. She is closely 
related to Chinnamunda – the severed-headed form of the Tibetan Buddhist
 goddess Vajrayogini.

Chhinnamasta is described as being as red as the hibiscus flower or as 
bright as a million suns. She is depicted mostly nude and with 
dishevelled hair. She is described to be a sixteen-year-old girl with 
full breasts, having a blue lotus near her heart. Chhinnamasta is 
depicted wearing a serpent as a sacred thread and a garland of 
skulls/severed heads and bones, along with other ornaments around her 
neck. She carries her own severed head – sometimes in a platter or a 
skull-bowl – in her left hand and holding a khatri, a scimitar or knife 
or scissor-like object, in her right hand, by which she decapitated 
herself. A crown on the severed head and bangles, waist-belt ornaments 
may be also depicted. Three streams of blood string from her neck, one 
enters her own mouth, while the others are drunk by her female yogini 
companions, who flank her. Both the attendants – Dakini to her left and 
Varnini to her right – are depicted nude, with matted or dishevelled 
hair, three-eyed, full-breasted, wearing the serpentine sacred thread 
and carrying the skull-bowl in the left hand and the knife in the right.
 While Dakini is fair and represents the tamas guna, Varnini is 
red-complexioned and conveys the rajas guna. With her right leg 
stretched and left leg bent a little, Chhinnamasta stands in a fighting 
posture on the love-deity couple of Kamadeva (Kama) – a symbol of sexual
 lust – and his wife Rati, who are engrossed in copulation with the 
latter usually on the top (viparita-rati sex position). Below the couple
 is a lotus and in the background is a cremation ground.[20][25][26][27]
 This popular iconographic form is described in the Tantrasara and the 
Trishakti Tantra.[20]
Sometimes, the attendants also hold severed heads (not their own).[28] 
Sometimes, Kamadeva-Rati is replaced by the divine couple of Krishna and
 Radha.[15] The lotus beneath the couple is sometimes replaced by a 
cremation pyre. The coupling couple is sometimes omitted completely. 
Sometimes, Shiva – the goddess's consort – is depicted lying beneath 
Chhinnamasta, who is seated squatting on him and copulating with 
him.[29]
Chhinnamasta's popular iconography is similar to the yellow coloured 
severed-head form of the Buddhist goddess Vajrayogini, except the 
copulating couple – which is exclusive to the former's iconography – and
 Chhinnamasta's red skin tone.[5][6]
Chhinnamasta Tantra describes the goddess sitting on Kamadeva, rather 
than standing on him. Additionally, she is described as three-eyed, with
 a jewel on her forehead, which is tied to a snake and her breasts 
adorned with lotuses.[20] Another form of the goddess in the Tantrasara 
describes her seated in her own navel, formless and invisible. This form
 is said to be only realised via a trance.[20]
Sometimes, Chhinnamasta is depicted as four-armed, and without the 
copulating couple. She is depicted on a grass patch, holding the sword 
with dripping blood in her upper right hand, a breaded head – identified
 with Brahma – in the lower one. Her upper left hand carries her own 
severed head, spilling blood in a skull-cup in her lower hand. Her two 
attendants depicted as skeletons drinking the dripping blood, while two 
jackals drinking the blood dripping from the head of the goddess and 
Brahma.[30]
The scholar van Kooij notes that the iconography of Chhinnamasta have 
the elements of heroism (vira rasa) and terror (bhayanaka rasa) as well 
as eroticism (sringara rasa) in terms of the copulating couple, with the
 main motifs being the offering of her own severed head, the spilling 
and drinking of blood and the trampling of the couple.[31]
(...)
Chhinnamasta signifies that life, death and sex are interdependent. 
Chhinnamasta's image conveys the eternal truth that "life feeds on 
death, is nourished by death, necessitates death, and that the ultimate 
destiny of sex is to perpetuate more life, which in turn will decay and 
die in order to feed more life".[25] While the lotus and the lovemaking 
couple symbolize life and the urge to create life, in a way gives 
life-force to the beheaded goddess, the blood flowing from goddess 
conveys death and loss of the life-force, which flows into the mouths of
 her devotee yoginis, nourishing them.[25][32] The scholar P. Pal 
equates Chhinnamasta with the concept of sacrifice and renewal of 
creation. Chhinnamasta self-sacrifices herself and her blood – drunk by 
her attendants – nourishes the universe.[33] An invocation to her calls 
her the sacrifice, the sacrificer and the recipient of the sacrifice, 
with the severed head treated as an offering.[25][34][35]
While other fierce Hindu goddesses like Kali are depicting severing the 
heads of demons and are associated with ritual self-decapitation, 
Chhinnamasta's motif also reverses ritual head-offering, in which she 
offers her own head to the devotees (attendants) to feed them. In this 
way, she symbolizes the aspect of the Goddess as a giver. At the same 
time, she subdues and takes the life-force of the copulating divine 
couple, signifying the aspect of the life-taker like Kali.[6]
Chhinnamasta standing on a copulating couple of Kamadeva (literally 
"sexual desire") and Rati ("sexual intercourse") is interpreted by some 
as a symbol of self-control of sexual desire, while others interpret it 
as the goddess, being an embodiment of sexual energy. Her names like 
Yogini and Madanatura ("one who has control on Kama") convey her yogic 
control and restraint on sexual energy.[36] Images in which Chhinnamasta
 is depicted sitting on Kamadeva-Rati in a non-suppressive fashion, the 
couple giving sexual energy to the goddess, and where Shiva is depicted 
in coitus with Chhinnamasta are associated with the other 
interpretation. Chhinnamasta's names like Kameshwari ("goddess of 
desire") and Ratiragavivriddhini ("one who is engrossed in the realm of 
Rati – [copulation or sexual desire]") and the appearance of klim – the 
common seed syllable of Kamadeva and Krishna – in her mantra support 
this interpretation.[37]
Acarya Ananda Jha, the author of the Chinnamasta Tattva, prescribes her 
worship by soldiers as she embodies self-control of lust, heroic 
self-sacrifice for the benefit of others and fearlessness of death. Her 
nudity and headlessness symbolise her integrity and "heedlessness". Her 
names like Ranjaitri ("victorious in war") celebrate her as the slayer 
of various demons and her prowess in battle.[38]
The Chhinnamasta icon is also understood as a representation of the 
awakening of the kundalini – spiritual energy. The copulating couple 
represent the awakening in the Muladhara chakra, which corresponds to 
the last bone in the spinal cord. The kundalini flows through the 
central passage in the body – the Sushumna nadi and hitting the topmost 
chakra, the Sahasrara at the top of head – with such force that it blows
 her head out. The blood spilling from the throat applies the 
upward-flowing kundalini, breaking all knots (granthis) – which make a 
person sad, ignorant and weak – of the chakras. The severed head is 
"transcendent consciousness". The three blood streams is the flow of 
nectar when the kundalini unites with Shiva, who resides in the 
Sahasrara. Another interpretation associates Daknini, Varnini and 
Chhinnamasta with the three main subtle channels (nadis): Ida, Pingala 
and Sushumna flowing free.[39][40][41] Sushumna connects the Muladhara 
and Sahasrara and is cognate with the spinal cord. Ida courses from the 
right testicle to the left nostril and is linked to the cooling lunar 
energy and the right hand side of the brain. Pingala courses from the 
left testicle to the right nostril and is associated with the hot solar 
energy and the left hand side of the brain.
The self-decapitation also represents removal of false notions, 
ignorance and egoism. The ability to remain alive despite the beheading 
is associated to supernatural powers and awakening of the kundalini.[42]
 The triad of the goddess and the two yoginis is also philosophically 
cognate to the triad of patterns, "which creative energy is felt to 
adopt".[20]
(...)
While she is easily identified by most Hindus and often worshipped and 
depicted as part of the Mahavidya group in goddess temples, Chhinnamasta
 is not so popular as an individual goddess. Her individual temples as 
well as her public worship are rare. Her individual worship is 
restricted to heroic, Tantric worship by Tantrikas (a type of Tantric 
practitioners), yogis and world renouncers. The lack of her worship is 
attributed by Kinsley to her ferocious nature and her reputation of 
being dangerous to approach and worship.[9][43] Her hundred-name hymn 
and thousand-name hymn describe her fierce nature and wrath. The names 
describe her as served by ghosts and as gulping blood. She is pleased by
 human blood, human flesh and meat, and worshipped by body hair, flesh 
and fierce mantras.[43]
Tantric practitioners worship Chhinnamasta for acquiring siddhis or 
supernatural powers.[9] Chhinnamasta's mantra Srim hrim klim aim 
Vajravairocaniye hum hum phat svaha is to be invoked to attract and 
subjugate women.[44][45] Another goal of her worship is to cast spells 
and cause harm to someone.[20] Other goals common to worship of all 
mahavidyas are: poetic speech, well-being, control of one's foes, 
removal of obstacles, ability to sway kings, ability to attract others, 
conquest over other kings and finally, moksha (salvation).[43][46]
The Tantric texts Tantrasara, Shakta-pramoda and Mantra-mahodadhih (1589
 CE)[47] give details about the worship of Chhinnamasta and other 
Mahavidyas, including her yantra, mantra and her meditative/iconographic
 forms (dhyanas).[43] Tantric texts tells the worshipper to imagine a 
red sun orb – signifying a yoni triangle – in his own navel. In the orb,
 the popular form of Chhinnamasta is imagined to reside.[20] Tantrasara 
cautions a householder-man to invoke the goddess only in "abstract 
terms". It further tells that if woman invokes Chhinnamasta by her 
mantra, the woman will become a dakini and lose her husband and son, 
thereby becoming a perfect yogini.[20] Shaktisamgama-tantra prescribes 
her worship only by the left-handed path (Vamamarga). Mantra-mahodadhih 
declares that such worship involves having sexual intercourse with a 
woman, who is not one's wife. Shakta-pramoda tells the same, adding fire
 offerings, wine and meat offerings at night.[48] Some hymns narrate 
that she likes blood and as such, is offered blood sacrifices at some 
shrines.[49] Shaktisamgama-tantra says that only brave souls (viras) 
should follow Vamamarga worship to the goddess. Shakta-pramoda warns 
that improper worship would have severe consequences: Chhinnamasta would
 severe the head of such a person and drink his blood. It further 
categorizes worship for Chhinnamasta to followed by householders and 
renouncers.[48]
The Chintapurni, Himachal Pradesh temple to Chhinnamasta claims to be 
one of the Shakti Peeths and where the goddess Sati's forehead (mastaka)
 fell. Here, Chhinnamasta is interpreted as the severed-headed one as 
well as the foreheaded-one.[50] A shrine dedicated to Chhinnamasta 
exists in Ramnagar, near Varanasi, where tantrikas worship her using 
corpses. There are Chhinnamasta shrines in Jharkhand (formerly Bihar) on
 the hill Nandan Parvat near Deoghar (Vaidyanath) and in Ranchi, along 
with other Mahavidyas. Her shrine is situated in the Kamakhya Temple 
complex, Assam, along with other Mahavidyas. A temple to Chhinnamasta is
 present in Vishnupur (Bishnupur), West Bengal. Chhinnamasta's shrines 
are also found in Nepal's Kathmandu Valley, notably near the Changu 
Narayan temple. The earliest of these temples is dated by Benard to the 
late 17th century.[48][51][52]

    One day Parvati went to bathe in the Mandakini River with her two 
attendants, Jaya and Vijaya. After bathing, the great goddess's color 
became black because she was sexually aroused. After some time, her two 
attendants asked her, "Give us some food. We are hungry." She replied, 
"I shall give you food but please wait." After awhile, again they asked 
her. She replied, "Please wait, I am thinking about some matters." 
Waiting awhile, they implored her, "You are the mother of the universe. A
 child asks everything from her mother. The mother gives her children 
not only food but also coverings for the body. So that is why we are 
praying to you for food. You are known for your mercy; please give us 
food." Hearing this, the consort of Shiva told them that she would give 
anything when they reached home. But again her two attendants begged 
her, "We are overpowered with hunger, O Mother of the Universe. Give us 
food so we may be satisfied, O Merciful One, Bestower of Boons and 
Fulfiller of Desires."
Hearing this true statement, the merciful goddess smiled and severed her
 own head. As soon as she severed her head, it fell on the palm of her 
left hand. Three bloodstreams emerged from her throat; the left and 
right fell respectively into the mouths of her flanking attendants and 
the center one fell into her mouth.
After performing this, all were satisfied and later returned home. (From
 this act) Parvati became known as Chinnamasta.
In visual imagery, Chinnamasta is shown standing on the copulating 
couple of Kamadeva and Rati, with Rati on the top. They are shown lying 
on a lotus.
There are two different interpretations of this aspect of Chinnamasta's 
iconography. One understands it as a symbol of control of sexual desire,
 the other as a symbol of the goddess's embodiment of sexual energy.
The most common interpretation is one where she is believed to be 
defeating what Kamadeva and Rati represent, namely sexual desire and 
energy. In this school of thought she signifies self-control, believed 
to be the hallmark of a successful yogi.
The other, quite different interpretation states that the presence of 
the copulating couple is a symbol of the goddess being charged by their 
sexual energy. Just as a lotus seat is believed to confer upon the deity
 seated atop it's qualities of auspiciousness and purity, Kamadeva and 
Rati impart to the Goddess standing over them the power and energy 
generated by their lovemaking. Gushing up through her body, this energy 
spouts out of her headless torso to feed her devotees and also replenish
 herself. Significantly here the mating couple is not opposed to the 
goddess, but an integral part of the rhythmic flow of energy making up 
the Chinnamasta icon.
The image of Chinnamasta is a composite one, conveying reality as an 
amalgamation of sex, death, creation, destruction and regeneration. It 
is stunning representation of the fact that life, sex, and death are an 
intrinsic part of the grand unified scheme that makes up the manifested 
universe. The stark contrasts in this iconographic scenario-the gruesome
 decapitation, the copulating couple, the drinking of fresh blood, all 
arranged in a delicate, harmonious pattern - jolt the viewer into an 
awareness of the truths that life feeds on death, is nourished by death,
 and necessitates death and that the ultimate destiny of sex is to 
perpetuate more life, which in turn will decay and die in order to feed 
more life. As arranged in most renditions of the icon, the lotus and the
 pairing couple appear to channel a powerful life force into the 
goddess. The couple enjoying sex convey an insistent, vital urge to the 
goddess; they seem to pump her with energy. And at the top, like an 
overflowing fountain, her blood spurts from her severed neck, the life 
force leaving her, but streaming into the mouths of her devotees (and 
into her own mouth as well) to nourish and sustain them. The cycle is 
starkly portrayed: life (the couple making love), death (the decapitated
 goddess), and nourishment (the flanking yoginis drinking her blood).

    Skt., cinnamasta: Headless One
"She of the Cut Neck" or the "Headless One" is a goddess concerned with 
life, death and the idea of blood as a life-force. She represents the 
Shakti in her destructive and creative aspects, signifying apparent 
dissolution and return to what is called "the first cause".
In paintings she is most often presented as a woman with a severed head,
 two streams of blood flowing from her neck, bestowing her own 
life-force unto Varnani and Dakini, the two female figures beside her. 
It is she who distributes "vital essence" or "life energy" to all 
beings. The whole scene described here is set inside a huge lotus which 
arises from the union of a male & female pair; Rati and Kama, the 
god of love & desire.
Sometimes Chinnamasta is identified with, or seen as, an aspect of 
either Durga or Kali, and there are clear connections as well to the 
Buddhist Vajrayogini.
Chinnamasta is also known as Viraratri.

    "Guptadurge Mahabhage Guptapaapapranashini
Saptajanmaarjitat Paapaat Traahi Maam Saranagatam"
Chhinnamasta, "She who severs her own head", is also called 
Chhinnamastika or Prachanda Chandika. This tantric goddesses is a 
ferocious aspect of the Devi and can be identified by her fearsome 
iconography.
This self-decapitated goddess holds her own severed head in one hand and
 a scimitar in the other. Three jets of blood spurt out of her bleeding 
neck, which is drunk by her own severed head and two attendants standing
 by each side of her. Chhinnamasta is also usually portrayed as standing
 on a copulating couple.
As the figure of Chhinnamasta suggests, this particular Mahavidya is 
associated with the concept of self-sacrifice as well as the awakening 
of the kundalini - the spiritual energy lying dormant within the 
Sookshma Sharira (subtle body). Chhinnamasta is a mixture of 
contradictions. She is regarded both as a symbol of self-control on 
sexual desire as well as an embodiment of sexual energy, depending upon 
the interpretation of the devotee.
As Chhinnamasta is considered a dark and dangerous deity, she has few 
temples, mostly found in North India and Nepal. Her individual worship 
is restricted to Tantric worship by Tantrikas and yogis.
Interestingly, Chhinnamasta is recognized by Hindus as well as 
Buddhists. She is closely related to Chinnamunda - the severed-headed 
form of the Tibetan Buddhist goddess Vajrayogini.
Physical attributes
Chhinnamasta is shown as being red like the hibiscus flower and as 
bright as a million suns. Portrayed mostly nude, with dishevelled hair, 
she is considered to be a sixteen-year-old girl with full breasts, 
having a blue lotus near her heart. Chhinnamasta is also depicted 
donning a serpent as a sacred thread and a garland of skulls/severed 
heads, bones and other ornaments around her neck.
She carries her own severed head in her left hand and holds a khatri or 
scimitar-like object in her right hand, by which she decapitated 
herself. Three streams of blood string from her neck, one of which 
enters her own mouth. The others are drunk by her female companions.
Both the attendants are depicted nude as well, with three-eyes, wearing 
the serpentine sacred thread and carrying the skull-bowl in the left 
hand and the knife in the right. While Dakini is light-skinned and 
represents the tamas guna, Varnini is red-complexioned and embodies the 
rajas guna.
Chhinnamasta is often shown standing on Kamadeva (the god of Love) and 
his wife Rati, who are engrossed in copulation with the latter, usually 
on top. Below the couple lies a lotus and in the background is a 
cremation ground. The copulating couple is sometimes different and 
sometimes, completely absent.
Legend of Chhinnamasta's birth
According to one legend from the Pranotasani Tantra, Parvati, while once
 having a bath in the Mandakini river, becomes sexually excited, making 
her skin turn black. At this time, her two female attendants Dakini and 
Varnini also become extremely hungry and beg for food. Though Parvati 
initially promises to give them food once they get back home, she 
decides to behead herself by means of using her nails and gives them her
 blood to satiate their hunger.
The other story is narrated by Shiva. His consort Chandika (also an 
aspect of Parvati) was engrossed in coitus with him in reverse posture, 
but became angry at his seminal emission. Her attendants Dakini and 
Varnini rose from her body. The rest of the story is similar to the 
earlier version.
There is yet another legend that relates how the goddess 
Prachanda-Chandika helped the gods slay all the evil demons. The enraged
 goddess then cut off her own head too and drinks her own blood.
Her name also appears in the Samudra Manthan episode (Churning of 
Ocean), where Chhinnamasta drinks up the demons' share of  the Devamruta
 (divine elixir of youth) and then beheads herself to prevent the demons
 from acquiring the same.
Relevance and symbolism of Chhinnamasta
Chhinnamasta signifies that life, death and sex are interdependent. Her 
image embodies the eternal truth that life feeds on death and that the 
ultimate destiny of sex is to perpetuate more life, which in turn will 
decay and die in order to feed more life. The lotus and the copulating 
couple symbolize life and the urge to procreate. The blood flowing from 
goddess' neck conveys death, which flows into the mouths of her 
devotees, nourishing them. This symbolizes the aspect of the Goddess as a
 giver.
In a spiritual context, the image of Chhinnamasta is a representation of
 the awakening of the kundalini. The lovemaking couple actually 
represents the awakening in the Muladhara chakra. The kundalini flows 
through the central passage in the body. The blood spilling from the 
throat depicts the upward-flowing kundalini, breaking all obstacles and 
finally resulting in enlightenment.
The severed head shows the transcendent consciousness. Daknini, Varnini 
and Chhinnamasta can be related to the three main subtle nadis or 
channels, namely, Ida, Pingala and Sushumna. The self-decapitation also 
represents removal of ignorance and ego.

    Chinnamasta, the ‘severed headed’ yogini, who traditionally appears 
as  the third of the ten mahavidyas or ‘great knowledge-holding’ 
goddesses  in the Hindu shakta-tantra traditions. Collectively the ten 
mahavidyas  represent the various manifestation of the great goddess 
Devi or Durga,  who assumed these powerful and often terrifying aspects 
in order to  pacify, subjugate or destroy some of the most potent and 
malevolent  forces in the universe.
Chinnamasta and her two attendants appear  amidst a blazing mass of 
wisdom fire as they dance above the copulating  forms of white Shiva and
 red Parvati, who lie together upon the  patterned golden sun disc of a 
multicoloured lotus. In reversed sexual  posture Parvati lies on top of 
Shiva, her naked body adorned with gold  and bone ornaments, her hair 
loosened, her three eyes gazing  passionately at his face, and her hand 
pressing upon his hip. Shiva’s  legs are spread wide as he fondles 
Parvati’s breast, his tiger-skin  loincloth loosened, and his body 
adorned with rudraksha beads and the  great naga-serpent Vasuki, who 
coils around his neck. Shiva has three  eyes, his forehead is marked 
with a tripundra, and his long matted  hair-locks are crowned with a 
crescent moon and the cascading waters of  the river-goddess Ganga.
Chinnamasta is deep red in colour,  youthful, beautiful, passionate, and
 radiant like a million suns as she  ecstatically dances in pratyalidha 
posture, with her right leg bent and  her left leg extended. With her 
right hand she wields aloft the  bloodstained curved knife with which 
she has just severed her own head,  her index finger raised in the 
threatening tarjani gesture. And with her  outstretched left hand she 
holds aloft a skull-cup that contains her  own freshly severed and 
blood-dripping head, its three eyes gazing  upward, its mouth wide open 
as her long tongue receives the stream of  blood that cascades from the 
severed central vein of her neck. Her  severed head is adorned by a 
golden crown with five jewel-topped skulls,  and encircled by a blazing 
halo of yellow fire. Her naked body is  adorned with ornaments of gold 
and filigree bone. Around her neck she  wears a golden choker, a pearl 
necklace, a chained golden pendant, and a  garland of fifty white 
skulls. And around her waist is a bone apron of  small bone beads, with 
sixty-four intricate loops that bear the carved  bone ornaments of 
little skulls, crossed-vajras, pendants, and hanging  bells. The soles 
of her feet are marked with henna patterns of wheels,  tridents and 
lotuses, whilst fire radiates from the dancing feet of both  Chinnamasta
 and her attendants.
Her two attendants, red Varini  and blue-black Dakini, lean outward at 
Chinnamasta’s right and left  sides, each with their own fiery aura and 
blazing halo. These two naked  goddesses are similar in appearance to 
Chinnamasta, with disheveled  hair, gold and bone ornaments, 
blood-smeared cheeks and breasts, and  they both hold a curved knife and
 a skull-cup of blood in their right  and left hands. With protruding 
tongues they drink the streams of blood  that squirt from the severed 
right and left veins of Chinnamasta’s neck.  Symbolically, these three 
blood-spurting veins represent the  unobstructed psychic energies of the
 subtle-body’s median nerve or  central channel, with its two subsidiary
 solar and lunar channels, which  are respectively personified in the 
forms of Chinnamasta, Varini, and  Dakini.
Above Chinnamasta’s neck is her yantra or ‘diagram’,  which appears as a
 pink eight-petal lotus disc with a green seed-head,  upon which are two
 interlocking gold and red triangles, and an  upward-pointing inner 
golden triangle that is embossed with her  bija-mantra or seed-syllable,
 KRIM. Her yantra’s outer square or  bhupura, with its four directional 
gateways, is also embossed with  scrolling golden patterns. Her inner 
aura is decorated with an assembly  of mythical creatures and beings, 
which include: a makara, asura  warriors, a dancing skeleton and khyak 
spirit to her right; and an  elephant, a naga-queen, a wealth god, and a
 garuda wrestling with two  naga-serpents to her left. Her outer aura is
 decorated with a ring of  golden skulls and scrolling motifs.
Above Chinnamasta’s yantra is  the golden lotus and sun disc of Dakshina
 Kali, who squats upon the  quiescent white ‘corpse’ of Shiva as she 
passionately copulates with  him. Kali is wrathful, intoxicated, 
blue-black in colour, with four  arms, and three piercing eyes. Her 
disheveled locks of matted hair  billow outward behind her back, her 
cheeks and breasts are smeared with  blood, and her long bloodstained 
tongue hangs from her gaping mouth. She  wears ornaments of gold and 
bone, a severed head garland, an apron of  thirteen severed forearms, 
and a white crescent moon adorns her brow.  With her two right hands she
 makes the boon-granting varada-mudra and  the abhaya-mudra of 
protection, and with her two left hands she holds  the severed head of 
an enemy and a sword. Above Kali’s head is her  yantra, which appears as
 a nine-fold downward-pointing triangle at the  centre of an eight-petal
 lotus, with an outer black bhupura. Another  large and fiery yantra 
appears behind her back, with its blazing central  dais forming the 
circle of her aura, and its fiery bhupura merging with  the mass of 
twisting flames and billowing smoke that fills the sky.
The  lower landscape illustrates the environment of Pashupatinath 
Temple,  which is the most important Shaivite Temple in Nepal, and a 
famous  pilgrimage site for all Hindus in general. The temple is 
dedicated to  Shiva in his aspect as the ‘Lord (nath), who is the 
supreme lord (pati)  of all cattle (pashu) or creatures’. Pashupati 
stands upon the eastern  bank of the Bagmati River, which flows towards 
India as a tributary of  the River Ganges, and is thus also the most 
sacred Hindu cremation  ground in Nepal.
Samundra has depicted Pashupatinath as it may  have appeared during the 
nineteenth century, with its four circular  cremation platforms or 
burning-ghats separated by the steps that lead  down to the Bagmati 
River. At this time the western bank of the river  was believed to be 
haunted by ghosts and spirits, so upon this bank  appear the small 
figures of a male khyak spirit and a dancing yakshini,  both of whom are
 depicted with protruding tongues. The two-tiered temple  of 
Pashupatinath appears amidst the trees to the right, with its lion  
guardians, gilded roof and doorway, and several small white Shaivite  
temples in front of it. In the foreground are a group of sixteen male  
mourners who tearfully attend the cremation of an elderly man, while his
  widow performs sati by ritually offering herself to the flames of her 
 husband’s funeral pyre.
