CC Ādi 17.113
kabhu bheda dekhi, ei māyāya tomāra
“I am certain that Your form and the form I saw in my meditation are one and the same. If I see any difference, this is an act of Your illusory energy.”
Śrī-kṛṣṇa-caitanya rādhā-kṛṣṇa nahe anya: in the vision of a perfect devotee, Lord Caitanya Mahāprabhu is a combination of Rādhā and Kṛṣṇa. One who sees Lord Caitanya to be different from Kṛṣṇa is under the illusory energy of the Lord. It appears that the astrologer was already an advanced devotee, and when he came into the presence of the Supreme Lord Śrī Caitanya Mahāprabhu, he became perfectly self-realized and could see that the Supreme Personality of Godhead Kṛṣṇa and Śrī Caitanya Mahāprabhu are one and the same Supreme Person.
