Of the many objects of favored delight and of all the lovable gopis of Vraja, Radha is certainly the most treasured object of Krishna’s love. And, in every respect, Her divine kunda is described by great sages as similarly dear to Him. Undoubtedly Radha-kunda is very rarely attained even by the great devotees; therefore it is even more difficult for ordinary devotees to attain. If one simply bathes once within those holy waters, one’s pure love of Krishna is fully aroused.
