Revati as Srimati Jahnava Devi in Caitanya Lila

Balaram’s wives Varuni and Revati became Vasudha and Jahnavi, the two wives of Nityananda Prabhu, in Chaitanya-lila. Both of them were the daughters of Surya Das, who was as effulgent as the sun. He was Kakudman, the father of Revati, in his previous birth. According to another opinion, Jahnava was the incarnation of Ananga Mjari. Both these opinions are possible, as we have shown that more than one identity can be joined in associates of Chaitanya Mahaprabhu.
(Gaura-ganoddesha-dipika 65-6)

In a dream, Surya Das also had a vision of Nityananda as Balaram with Vasudha and Jahnava standing to his left and right in their forms as Revati and Varuni. When Surya Das took the Brahmin’s advice seriously and offered the two girls to Nityananda’s lotus feet, Nityananda Prabhu mercifully gave him the same vision directly. Surya Das fainted in ecstasy.

He saw Vasudha and Jahnava as Varuni and Revati, whose forms were more effulgent than mountains of gold and kunkum. Standing to the left and right of Balaram, they were decorated in magnificent jewelry and bedecked in fine, colorful clothes. Nityananda revealed this magnificence to his devotee in order to give him joy, and Surya Das completely forgot himself in his ecstasy.
