CC Adi-lila

By the will of Lord Caitanya, Śacīdevī invited Nityānanda to take prasādam at her house. Thus Viśvambhara (Lord Caitanya) and Nityānanda were eating together, and Śacīdevī realized that They were none other than Kṛṣṇa and Balarāma. Seeing this, she fainted.

CC Adi 17.17, Translation and Purport:

Thereafter mother Śacīdevī saw the brothers Kṛṣṇa and Balarāma in Their manifestation of Lord Caitanya and Nityānanda. Then the Lord delivered the two brothers Jagāi and Mādhāi.

One night Śacīdevī dreamt that the Deities in her house, Kṛṣṇa and Balarāma, had taken the forms of Caitanya and Nityānanda and were fighting one another, as children do, to eat the naivedya, or offering to the Deities. The next day, by the will of Lord Caitanya, Śacīdevī invited Nityānanda to take prasādam at her house. Thus Viśvambhara (Lord Caitanya) and Nityānanda were eating together, and Śacīdevī realized that They were none other than Kṛṣṇa and Balarāma. Seeing this, she fainted.

Jagāi and Mādhāi were two brothers born in Navadvīpa in a respectable brāhmaṇa family who later became addicted to all kinds of sinful activities. By the order of Lord Caitanya, both Nityānanda Prabhu and Haridāsa Ṭhākura used to preach the cult of Kṛṣṇa consciousness door to door. In the course of such preaching they found Jagāi and Mādhāi, two maddened drunken brothers, who, upon seeing them, began to chase them. On the next day, Mādhāi struck Nityānanda Prabhu on the head with a piece of earthen pot, thus drawing blood. When Śrī Caitanya Mahāprabhu heard of this, He immediately came to the spot, ready to punish both brothers, but when the all-merciful Lord Gaurāṅga saw Jagāi's repentant behavior, He immediately embraced him. By seeing the Supreme Personality of Godhead face to face and embracing Him, both the sinful brothers were at once cleansed. Thus they received initiation into the chanting of the Hare Kṛṣṇa mahā-mantra from the Lord and were delivered.
