Kālī is the Hindu goddess associated with empowerment, shakti. She is the fierce aspect of the goddess Durga (Parvati). The name Kali comes from kāla, which means black, time, death, lord of death: Shiva. Since Shiva is called Kāla— the eternal time — the name of Kālī, his consort, also means "Time" or "Death" (as in "time has come").
