Kalavati, the mother of Radha, was born from the fire altar
(from Yajna) at Kanyakubja (modern Kannauj). This is mentioned in the Brahma Vaivarta
Purana Sri Krishna Khanda (17.119 – 122).
King Bhanandana performed a yajna to appease the elements of
nature to get peace and prosperity in this land. At the end of the yajna, a baby
came out of the vedic altar smiling. The child was in the milk-sucking stage of
life. Wife of King Bhanandana, Malavati, took the girl in her bosom and adopted
her.
Thus Radha who was later to become the consort of Sri
Krishna was born ayonija (not from the female organ). Therefore it is pretty
sure that Radha was a manifestation of Goddess Lakshmi.
