Sri Kesava Bharati was a member of the Sankarite renunciate order. He bestowed sannyasa on Chaitanya Mahaprabhu when the latter requested it. In the Sri-Gaura-Ganoddesa-dipika of Kavi-karnapura, Kesava Bharati is listed as the reincarnation of Sandipani Muni.

Sakti

All manifestations of Vishnu tattva have three energies, known as Sri, Bhu and Nila (or Lila).

1. Lakshmipriya Devi is the sri-sakti of Mahaprabhu in his majestic Gaura-Narayan attitude; 
2. Vishnupriya is his bhu-sakti and 
3. Nabadwip Dham is his lila-sakti.
