From the book “Sri Vraja-maṇḍala-parikramā”:
The temple of Kaṅkālī–devī is found on Kaṅkālī–ṭīlā. She is called Kaṁsa–kālī or Kaṅkālī–devī, because Kaṁsa worshipped her. This is the same eight–armed Durgā–devī who rides a lion, that Kaṁsa wanted to kill thinking her to be the daughter of Devakī. But the goddess escaped from his hands and ascended into the sky.
Rajashekhara Dasa
From the book “Chaurasi-kosa Vraja Mandala Parikrama”:
This Deity of Kali Mata is said to have been personally worshiped by King Kamsa. The name ‘Kankali’ is derived from ‘Kamsa-Kali’ meaning ‘the Kali worshiped by Kamsa’. The temple is located on a small hill known as Kankali-tila.
