CC Madhya 3.66
ācāryera manaḥ-kathā nahe prabhura vedya
When Śrī Caitanya Mahāprabhu entered the room, He saw three divisions of food, and He knew that all of these were meant for Kṛṣṇa. However, He did not understand the intentions of Advaita Ācārya.
Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura states that one of these servings was offered in a metal dish and was meant for Kṛṣṇa, whereas the other two were placed on big banana leaves. The offering on the metal plate was personally offered by Advaita Ācārya to Kṛṣṇa. The other two servings, on banana leaves, were to be accepted by Śrī Caitanya Mahāprabhu and Lord Nityānanda. That was Advaita Ācārya’s intention, but He did not disclose this to Śrī Caitanya Mahāprabhu. Thus when Śrī Caitanya Mahāprabhu saw the food offered in three places, He thought that all of it was meant for Kṛṣṇa.
