Origins

Although the word Kālī appears as early as the Atharva Veda, the first use of it as a proper name is in the Kathaka Grhya Sutra (19.7). Kali originated as a tantric and non-Vedic goddess. Her roots are most probably connected to the Pre-Aryan period. According to Indologist Wendy Doniger, Kali’s origins can be traced to the deities of the Pre-Vedic village, tribal, and mountain cultures of South Asia who were gradually appropriated and transformed by the Sanskritic traditions.
