According to various myths and traditions, there are 51 pieces of Sati’s body scattered across the Indian subcontinent. These places are called shakti peethas and are dedicated to various powerful goddesses. Kamarupa is the region in which the yoni is said to have fallen to earth, and the Kamakhya temple was said to have been constructed on this spot.
Kamakhya is mentioned in the Kalika Purana as the most important goddess of Tantric worship, and is referred to in the text as Mahamaya, the “great goddess of illusion”, who takes on many forms depending on her mood. Devotees also call her Kameshwari (“beloved goddess of desire”), and consider her a form of Maha Tripura Sundari, also called Shodashi. She is identified with Kali in the Kalika Purana, Yoginitantra and Kamakhya Tantra, each of which echoes this verse:
The origin of worship ‘Shakti’ at the site is associated with the legend of Sati, who was the wife of the ascetic god Shiva and daughter of the Puranic god-king Daksha. Daksha was unhappy with his daughter’s choice of husband, and when he performed a grand Yajna for all the deities, he did not invite Shiva or Sati. In a rage, Sati threw herself onto the fire, knowing that this would make the sacrifice impure. Because she was the all-powerful mother goddess, Sati left her body in that moment to be reborn as the goddess Parvati. Meanwhile, Shiva was stricken with grief and rage at the loss of his wife. He put Sati’s body over his shoulder and began his tandava (dance of cosmic destruction) throughout the heavens, and vowed not to stop until the body was completely rotted away. The other Gods, afraid of their annihilation, implored Vishnu to pacify Shiva. Thus, wherever Shiva wandered while dancing, Vishnu followed. He sent his discus Sudarshana to destroy the corpse of Sati. Pieces of her body fell until Shiva was left without a body to carry. Seeing this, Shiva sat down to do Mahatapasya (great penance). Despite the similarity in name, scholars do not generally believe that this legend gave rise to the practice of sati or the voluntary giving of the wife’s body on the pyre of her husband .
