CC Antya 3.31
bāhya virahe tāhā svapna kari māna
“ ‘You know that I come and eat the offerings, but because of external separation, you consider this a dream.
Because mother Śacī was feeling separation from Śrī Caitanya Mahāprabhu, she thought she was dreaming that her son had come to her. Śrī Caitanya Mahāprabhu, however, wanted to inform her that actually it was not a dream. He actually came there and ate whatever His mother offered Him. Such are the dealings of advanced devotees with the Supreme Personality of Godhead. As stated in the Brahma-saṁhitā (5.38):
santaḥ sadaiva hṛdayeṣu vilokayanti
yaṁ śyāmasundaram acintya-guṇa-svarūpaṁ
govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
“I worship the primeval Lord, Govinda, who is always seen by the devotee whose eyes are anointed with the pulp of love. He is seen in His eternal form of Śyāmasundara, situated within the heart of the devotee.” Pure devotees realize dealings with the Lord on the transcendental plane, but because the devotees are still in the material world, they think that these are dreams. The Lord, however, talks with the advanced devotee, and the advanced devotee also sees Him. It is all factual; it is not a dream.
