CC Ādi 10.30
pitā kari’ yāṅre bale gaurāṅga-sundara
Śrī Ācārya Purandara, the ninth branch, was a constant associate of Lord Caitanya’s. The Lord accepted him as His father.
It is described in the Caitanya-bhāgavata that whenever Lord Caitanya Mahāprabhu visited the house of Rāghava Paṇḍita, He also visited Purandara Ācārya immediately upon receiving an invitation. Purandara Ācārya is to be considered most fortunate because the Lord used to greet him by addressing him as His father and embracing him in great love.
