Mahakali () is the Hindu goddess of time and death in the goddess-centric tradition of Shaktism.
Similar to Kali, Mahakali is a fierce goddess associated with universal power, time, life, death, and both rebirth and liberation. She is the consort of Bhairava, the god of consciousness, the basis of reality and existence. Mahakali, in Sanskrit, is etymologically the feminised variant of Mahakala, or Great Time (which is also interpreted as Death), an epithet of the deities Narasimha and Shiva in Hinduism.
Meaning
Mahakali's origin is contained in various Puranic and Tantric Hindu Scriptures (Shastras). In the texts of Shaktism, she is variously portrayed as the Adi-Shakti, the Primeval Force of the Universe, identical with the Ultimate Reality, or Brahman. She is also known as the (female) Prakriti or World as opposed to the (male) Purusha or Consciousness, or as one of three manifestations of Mahadevi (The Great Goddess) that represent the three Gunas or attributes in Samkhya philosophy. In this interpretation Mahakali represents Tamas or the force of inertia. A common understanding of the Devi Mahatmya ("Greatness of the Goddess") text, a later interpolation into the Markandeya Purana, considered a core text of Shaktism (the branch of Hinduism which considers Durga to be the highest aspect of Godhead), assigns a different form of the Goddess (Mahasaraswati, Mahalakshmi, and Mahakali) to each of the three episodes therein. Here, Mahakali is assigned to the first episode. She is described as an abstract energy, the yoganidra of Vishnu.
Iconography
Mahakali is most often depicted in blue/black complexion in popular Indian art.
Her most common four armed iconographic image shows each hand carrying variously a crescent-shaped sword, a trishul (trident), a severed head of a demon and a bowl or skull-cup (kapala) catching the blood of the severed head. Her eyes are described as red with intoxication and in absolute rage, her hair is shown disheveled, small fangs sometimes protrude out of her mouth and her tongue is lolling. The blood of the demons she slays drips out of her lolling tongue, having consumed it. She is adorned with a garland consisting of the heads of demons she has slaughtered, variously enumerated at 108 (an auspicious number in Hinduism and the number of countable beads on a Japa Mala, similar to a rosary, for repetition of Mantras) or 50, which represents the letters of the Sanskrit alphabet, Devanagari, and wears a skirt made of demon arms.
Her ten headed (dashamukhi) image is known as the 10 Mahavidyas Mahakali, and in this form she is said to represent the ten Mahavidyas or "Great Wisdom (Goddess)s". She is sometimes shown sitting on a flaming grave or a rotting corpse. Her complexion is described as that of the night sky, devoid of stars. She is depicted in this form as having ten heads, thirty flaming eyes, ten arms, and ten legs but otherwise usually conforms to the four armed icon in other respects. Each of her ten hands is carrying an implement which varies in different accounts, but each of these represent the power of one of the devas, 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.
