Maa Kali is a ferocious form of goddess Mahadevi, the supreme of all powers, or the ultimate reality. She is the first of the ten Mahavidyas in the Hindu tantric tradition.
The goddess has two depictions: the popular four-armed form and the ten-armed Mahakali avatar. In both, she is described as being black in colour, though she is often seen as blue in popular Indian art. Her eyes are described as red with intoxication and rage. Her hair is disheveled, small fangs sometimes protrude out of her mouth, and her tongue is lolling. Sometimes she dons a skirt made of human arms and a garland of human heads. Other times, she is seen wearing a tiger skin. She is also accompanied by serpents and a jackal while standing on the calm and prostrate Shiva, usually right foot forward to symbolize the more popular daksinacara (“right-hand path”), as opposed to the more infamous and transgressive vamachara (“left-hand path”). These serpents and jackals are shown to drink the blood of Raktabija head, which is dripping while the goddess carries it in her hand, and preventing it from falling on the ground.
In the ten-armed form of Mahakali, she is depicted as shining like a blue stone. She has ten faces, ten feet, and three eyes for each head. She has ornaments decked on all her limbs. There is no association with Shiva.
The Kalika Purana describes Kali as possessing a soothing dark complexion, as perfectly beautiful, riding a lion, four-armed, holding a sword and blue lotus, while her right hands are in varabhaya posture, her hair unrestrained, body firm and youthful.
When Sri Ramakrishna once asked a devotee why one would prefer to worship Mother over him, this devotee rhetorically replied, “Maharaj, when they are in trouble your devotees come running to you. But, where do you run when you are in trouble?”
Classic depictions of Kali share several features, as follows:
Kali’s most common four armed iconographic image shows each hand carrying variously a Khadga (crescent-shaped sword or a giant sickle), a trishul (trident), a severed head, and a bowl or skull-cup (kapala) collecting the blood of the severed head. This is the form of Bhima Kali.
Two of these hands (usually the left) are holding a sword and a severed head. The sword signifies divine knowledge and the human head signifies human ego which must be slain by divine knowledge in order to attain moksha. The other two hands (usually the right) are in the abhaya (fearlessness) and varada (blessing) mudras, which means her initiated devotees (or anyone worshipping her with a true heart) will be saved as she will guide them here and in the hereafter. This is the form of Dakshina Kali.
She wears a garland of human heads, variously enumerated at 108 (an auspicious number in Hinduism and the number of countable beads on a japa mala or rosary for repetition of mantras) or 51, which represents Varnamala or the Garland of letters of the Sanskrit alphabet, Devanagari. Hindus believe Sanskrit is a language of dynamism, and each of these letters represents a form of energy, or a form of Kali. Therefore, she is generally seen as the mother of language, and all mantras.
She is often depicted naked which symbolizes her being beyond the covering of Maya since she is pure (nirguna) being-consciousness-bliss and far above Prakriti. She is shown as very dark as she is Brahman in its supreme unmanifest state. She has no permanent qualities—she will continue to exist even when the universe ends. It is therefore believed that the concepts of color, light, good, and bad do not apply to her.
Mahakali
Mahakali literally translated as “Great Kali,” is sometimes considered as a greater form of Kali, identified with the Ultimate reality of Brahman. It can also be used as an honorific of the Goddess Kali, signifying her greatness by the prefix “Maha”. Mahakali, in Sanskrit, is etymologically the feminized variant of Mahakala or Great Time (which is interpreted also as Death), an epithet of the God Shiva in Hinduism. Mahakali is the presiding Goddess of the first episode of the Devi Mahatmya. Here, she is depicted as Devi in her universal form as Shakti. Here Devi serves as the agent who allows the cosmic order to be restored.
Kali is depicted in the Mahakali form as having ten heads, ten arms, and ten legs. Each of her ten hands is carrying a various implement which varies in different accounts, but each of these represents the power of one of the Devas or Hindu Gods and are often the identifying weapon or ritual item of a given Deva. The implication is that Mahakali subsumes and is responsible for the powers that these deities possess and this is in line with the interpretation that Mahakali is identical with Brahman. While not displaying ten heads, an “ekamukhi” or one headed image may be displayed with ten arms, signifying the same concept: the powers of the various Gods come only through her grace.
Dakshinakali
Dakshinakali is the most popular form of Kali in Bengal. She is the benevolent mother, who protects her devotees and children from mishaps and misfortunes. There are various versions for the origin of the name Dakshinakali. Dakshina refers to the gift given to a priest before performing a ritual or to one’s guru. Such gifts are traditionally given with the right hand.
Dakshinakali’s two right hands are usually depicted in gestures of blessing and giving of boons. One version of the origin of her name comes from the story of Yama, lord of death, who lives in the south (dakshina). When Yama heard Kali’s name, he fled in terror, and so those who worship Kali are said to be able to overcome death itself.
Dakshinakali is typically shown with her right foot on Shiva’s chest—while depictions showing Kali with her left foot on Shiva’s chest depict the even more fearsome Vamakali.
The pose shows the conclusion of an episode in which Kali was rampaging out of control after destroying many demons. Lord Vishnu, Kali’s brother, confronted Kali in an attempt to cool her down. She was unable to see beyond the limitless power of her rage and Lord Vishnu had to move out of her way. Seeing this the devas became more fearful, afraid that in her rampage, Kali would not stop until she destroyed the entire universe. Shiva saw only one solution to prevent Kali’s endless destruction. Lord Shiva lay down on the battlefield so that Goddess Mahakali would have to step on him. When she saw her consort under her foot, Kali realized that she had gone too far. Filled with grief for the damage she had done, her blood-red tongue hung from her mouth, calming her down. In some interpretations of the story, Shiva was attempting to receive Kali’s grace by receiving her foot on his chest.
The goddess is generally worshiped as Dakshina Kali (with her right feet on Shiva) in Bengal during Kali Puja. There are many different interpretations of the pose held by Dakshinakali, including those of the 18th and 19th-century bhakti poet-devotees such as Ramprasad Sen. Some have to do with battle imagery and tantric metaphysics. The most popular is a devotional view.
According to Rachel Fell McDermott, the poets portrayed Shiva as “the devotee who falls at [Kali’s] feet in devotion, in the surrender of his ego, or in hopes of gaining moksha by her touch.” In fact, Shiva is said to have become so enchanted by Kali that he performed austerities to win her, and having received the treasure of her feet, held them against his heart in reverence.
The growing popularity of worship of a more benign form of Kali, Dakshinakali, is often attributed to Krishnananda Agamavagisha. He was a noted Bengali leader of the 17th century and author of a Tantra encyclopedia called Tantrasara. Kali reportedly appeared to him in a dream and told him to popularize her in a particular form that would appear to him the following day. The next morning he observed a young woman making cow dung patties. While placing a patty on a wall, she stood in the alidha pose, with her right foot forward. When she saw Krishnananda watching her, she was embarrassed and put her tongue between her teeth. Krishnananda took his previous worship of Kali out of the cremation grounds and into a more domestic setting.
Samhara Kali
Samhara Kali, also called Vama Kali, is the embodiment of the power of destruction. The chief goddess of Tantric texts, Samhara Kali is the most dangerous and powerful form of Kali. Samhara Kali takes form when Kali steps out with her left foot holding her sword in her right hand. She is the Kali of death, destruction and is worshiped by tantrics. As Samhara Kali she gives death and liberation. According to the Mahakala Samhita, Samhara Kali is two armed and black in complexion. She stands on a corpse and holds a freshly cut head and a plate to collect the dripping blood. She is worshiped by warriors, tantrics – the followers of Tantra.
