krsna-madhuryera eka adbhuta svabhava
apana asvadite krsna kare bhakta-bhava
krsna-madhuryera—the supreme pleasure potency of Krsna; eka—is one; adbhuta—wonderful; svabhava—nature; apana—Himself; asvadite—to taste; krsna—the Supreme Personality of Godhead; kare—does; bhakta-bhava—accept the form of a devotee.
The transcendental mellow of conjugal love of Krsna is so wonderful that Krsna Himself accepts the form of a devotee to relish and taste it fully.
Although Krsna is the reservoir of all pleasure, He has a special intention to taste Himself by accepting the form of a devotee. It is to be concluded that although Lord Caitanya is present in the form of a devotee, He is Krsna Himself. Therefore Vaisnavas sing, sri-krsna-caitanya radha-krsna nahe anya: Radha and Krsna combined together are Sri Krsna Caitanya Mahaprabhu. Caitanyakhyam prakatam adhuna tad-dvayam caikyam aptam. Sri Svarupa-damodara Gosvami has said that Radha and Krsna assumed oneness in the form of Sri Caitanya Mahaprabhu.
