Sri-krsna-caitanya radha-krsna nahe anya: in the vision of a perfect devotee, Lord Caitanya Mahaprabhu is a combination of Radha and Krsna. One who sees Lord Caitanya to be different from Krsna 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 Sri Caitanya Mahaprabhu, he became perfectly self-realized and could see that the Supreme Personality of Godhead Krsna and Sri Caitanya Mahaprabhu are one and the same Supreme Person.
