Chanting the Names Of Gaura Nitai

krishna nama kare aparadhera vicara
krishna balile aparadhira na haya vikara

"Because of making offenses when chanting the Hare Krishna maha mantra, one does not become ecstatic."
Caitanya Caritamrita, Adi 8.24

caitanya nityanande nahi esaba vicara
nama laite prema dena, vahe asrudhara
svatantra isvara prabhu atyanta udara
tanre na bhajile kabhu na haya nistara

"But if one chants the names of Lord Caitanya and Nityananda Prabhu, with just a little faith, very quickly all his/her offenses are cleared.
Then, when he/she chants the Hare Krishna mantra, the symptoms of ecstatic love will be felt. Sri Caitanya Mahaprabhu and Nityananda Raya are independent supreme personalities. They are infinitely generous.
No one can become free from their material karma unless they worship these two brothers."
Caitanaya Caritamrita Adi 8.31-32
