“yo ’si so ’si namo ’stu te” ei mantra paḍe mukha-vādya kari’ prabhu hāsāya ācāryere
Śrī Caitanya Mahāprabhu would worship Advaita Ācārya by chanting the mantra “Whatever You are, You are — but I offer My respects unto You.” In addition, the Lord would make some sounds within His mouth that would make Advaita Ācārya laugh.
