"Lord Krishna enchants the world, but Sri Radha enchants even Him. Therefore She is the supreme goddess of all.
"Sri Radha is the full power, and Lord Krishna is the possessor of full power. The two are not different, as evidenced by the revealed scriptures.
"They are indeed the same, just as musk and its scent are inseparable, or as fire and its heat are nondifferent.
"Thus Radha and Lord Krishna are one, yet They have taken two forms to enjoy the mellows of pastimes."
(Sri Caitanya Caritamrita, Adi-lila, 4.95-98)
