kṛṣṇa-kathāya - in the discussion on Kṛṣṇa; prabhura - of Śrī Caitanya Mahāprabhu; mahā-prema - great love; uthalila - arose; bhaṭṭera - of the Bhaṭṭācārya; saṅkoce - due to shyness; prabhu - Śrī Caitanya Mahāprabhu; samvaraṇa kaila - restrained Himself.

Śrī Caitanya Mahāprabhu felt great ecstatic love when they began discussing Kṛṣṇa, but the Lord checked His feelings because He felt shy before Vallabha Bhaṭṭa.
