"Dear Caitanya Mahāprabhu," they said, "to tell You the truth, we are greatly pleased to hear Your words, and furthermore Your bodily features are so pleasing that we feel extraordinary satisfaction in seeing You.
In the śāstras it is said:
na bhaved grāhyam indriyaiḥ
sevonmukhe hi jihvādau
svayam eva sphuraty adaḥ
"With one's materially contaminated senses one cannot understand the Supreme Personality of Godhead or His name, form, qualities or paraphernalia, but if one renders service unto Him the Lord reveals Himself." (Bhakti-rasāmṛta-sindhu 1.2.234) Here one can see the effect of the Māyāvādī sannyāsīs' service toward Nārāyaṇa. Because they offered a little respect to Śrī Caitanya Mahāprabhu and because they were pious and actually followed the austere rules and regulations of sannyāsa, they had some understanding of Vedānta philosophy, and by the grace of Lord Caitanya Mahāprabhu they could appreciate that He was none other than the Supreme Personality of Godhead, who is endowed with all six opulences. One of these opulences is His beauty. By His extraordinarily beautiful bodily features the Māyāvādī sannyāsīs recognized Śrī Caitanya Mahāprabhu as Nārāyaṇa Himself. He was not a farcical Nārāyaṇa like the daridra-nārāyaṇas invented by so-called sannyāsīs.
