‘kamalakanta visvasa’-nama acarya-kinkara
acarya-vyavahara saba—tanhara gocara
(C.C. Adi 12.28)
Advaita Acharya’s very confidential servant named Kamalakanta Vishvasa knew all the dealings of Advaita Acharya.
Shrila Prabhupada writes in the purport:
The name Kamalananda mentioned in the Adi-lila (10.149) and the name Kamalakanta mentioned in the Madhya-lila (10.94) both refer to the same man. Kamalakanta, a very confidential servant of Lord Chaitanya Mahaprabhu born in a brahmana family, engaged in the service of Shri Advaita Acharya as His secretary. When Paramananda Puri went from Navadwipa to Jagannatha Puri, he took Kamalakanta Vishvasa with him, and they both went to see Lord Chaitanya at Jagannatha Puri. It is mentioned in the Madhya-lila (10.94) that one of the Devotees of Lord Chaitanya, the brahmana Kamalakanta, went with Paramananda Puri to Jagannatha Puri.
