pradyumna-nṛsiṁhānanda āge kailā ‘āvirbhāva’
‘loka nistāriba’, — ei īśvara-svabhāva
Word for word: 
sākṣāt-darśane — by direct meeting; prāya — almost; saba — all; nistārilā — delivered; nakula-brahmacārīra — of a brahmacārī named Nakula; dehe — in the body; āviṣṭa ha-ilā — entered; pradyumna-nṛsiṁhānanda — Pradyumna Nṛsiṁhānanda; āge — in front of; kailā — made; āvirbhāva — appearance; loka nistāriba — I shall deliver all the fallen souls; ei — this; īśvara-svabhāva — the characteristic of the Supreme Personality of Godhead.
Translation: 
Śrī Caitanya Mahāprabhu delivered almost all the fallen souls by directly meeting them. He delivered others by entering the bodies of great devotees, such as Nakula Brahmacārī. And He delivered still others by appearing before them, as in the case of Nṛsiṁhānanda Brahmacārī. “I shall deliver the fallen souls.” This statement characterizes the Supreme Personality of Godhead.
Purport: 

The Lord always manifested His āvirbhāva appearance in the following four places: (1) the house of Śrīmatī Śacīmātā, (2) wherever Nityānanda Prabhu danced in ecstasy, (3) the house of Śrīvāsa (when kīrtana was performed), and (4) the house of Rāghava Paṇḍita. Lord Caitanya Himself appeared in these four places. (In this connection, one may consult text 34.)
