Bhaskararaya (Bhāskararāya Makhin) (1690–1785) is widely considered an authority on all questions pertaining to the worship of the Mother Goddess in Shaktism/Hinduism. He was born in Hyderabad, Telangana, was welcomed by king Serfoji II of Bhonsle dynasty in South India, and thereupon he settled in Tamil Nadu. According to Douglas Renfrew Brooks, a professor of Religion specializing in Shaktism studies, Bhaskararaya was "not only a brilliant interpreter of Srividya, he was an encyclopedic writer", and that he was a "thinker who had the wealth of Tantric and Vedic traditions at his fingertips". He belonged to the Srividya tradition of the Shakta Tantrism.

Bhaskararaya is the attributed author of more than 40 and range from Vedanta to poems of devotion and from Indian logic and Sanskrit grammar to the studies of Tantra. Several of his texts are considered particularly notable to the Shaktism tradition, one focussed on the Mother Goddess:
