During the Vrindavan Yatra of 1999 Radhanath Swami gave a very inspiring and spiritually surcharged class about how Radha kunda should be sought by all those who are serious in advancing spiritually. In the following excerpt taken from that talk, Radhanath Swami explains the supreme position of Sri Radha kunda.
Shri Chaitanya Mahaprabhu,who is none other than the Supreme Lord Sri Krishna in the compassionate mood of Srimati Radharani, invested within the heart of Rupa Goswami his own divine love and commissioned him to come to Vrindavan and reveal Vrindavan to the world. In Shri Updeshamruta(text 9) Srila Rupa Goswami has written about all holy places in this creation. It is said that Mathura Puri is most sacred because here the Supreme Lord Krishna appeared. Of all the places in Mathura Puri Vrindavan is more sacred because here Krishna performs the Rasa Lila or dances of Vraja. Of all places in forests of Vrindavan, Govardhan is most sacred because such very, very confidential pleasing pastimes are eternally being enacted here. Of all places of Govardhan, the supreme-most of all places in all the spiritual and material worlds is Sri Radha kunda, because it is at Radha-kunda that the highest divine loving relations of Sri Radha and Sri Krishna are enacted. For devotees what is highest is whatever gives Radha and Krishna most pleasure. Because They enjoy each other’s company with highest degree of ecstatic love at Radha kunda, it is considered holiest of all holy places in all of creation.
