Bhairavi is a fierce and terrifying aspect of the Devi virtually indistinguishable from Kali except for her particular identification as the consort of the Bhairava.
"My Mother is the principle of consciousness. She is Akhanda Satchidananda; indivisible Reality, Awareness, and Bliss. The night sky between the stars is perfectly black. The waters of the ocean depths are the same; The infinite is always mysteriously dark. This inebriating darkness is my beloved Kali."
-Ramakrishna
