Among the gopis, Srimati Radharani is the most dear to lord Krishna( as the most beloved of gopis).
According to nectar of instruction ‘chapter 9’, Rupa Goswami headed that superior to Mathura is vrindaban forest . And superior to forest is Govardhan Hill. And above all, the super excellent sri Radha Kund stands supreme, for it is over flooded with nectarian love of Krishna. Similarly,
Yathā  rādhā priyā visnos
tasyāh kundam priyam tathā
sarva-gopisu saivaika
visnor atyanta vallabho
    Just as Srimati Radharani is dear to Supreme lord krisna, so this kund is equally dear to Krishna. Among all gopis , She alone stands supreme as lord’s most beloved.
    It is mentioned in the Sastra ‘ that those who got chance even once to serve Radha Kunda, they are the most fortunate souls.’
    Sastra enlightened us that Srimati Radharani is certainly the most-treasured object of Krishna’s love. And her divine Kunda is also the object of Krishna’s love which is mentioned by different sages .
    Why Radha Kunda is so important?
    Radha kunda is so important because that contains the pure love for Krishna. Srimati Radharani and her divine Kunda is non-different. Radhakunda is very rare and even sages cannot find its   importance. There is  no questions to get it by ordinary devotees. Srila Bhaktivinoda Thakur mentioned that Radha Kunda is the most selected place to advance spirituality. He suggested to  reside in Radha KUnda if the living entities wants to go back to transcendental kingdom. Srila Bhaktisiddhanta Saraswati Thakur explains that even  great sages like Nanda doesn’t get opportunity to bathe in it. So, what to talk about ordinary ones? He also emphasized to reside in Radha Kunda and worship it. If by great fortune, if one takes   bath in Radhakunda, the transcendental love for godhead will automatically revoke. One should take bathe as much as possible. If one bathe  there regularly with unalloyed devotional feeling, it is sure that he/she will return back to godhead.
    Radha kunda contains the highest perfection of devotional service. No one can approach it without mercy of greatest gopis. Thus there is no limit to describe Radhakunda. We are not qualified to glorify it because we are lowest. It is the highest of all. By  serving Radha kunda one get opportunity to be the assistant of Shrimati Radharani. So, all glories to Srimati Radharani and her Kunda.

Radharani is the most holy, chaste, pure, pious and greatest of all divinities. And her kunda is as profoundly dear to Krishna.
