Why is Radha-kunda so exalted? The lake is so exalted because it belongs to Srimati Radharani, who is the most beloved object of Sri Krishna. Among all the gopis, She is the most beloved. Similarly, Her lake, Sri Radha-kunda, is also described by great sages as the lake that is as dear to Krishna as Radha Herself. Indeed, Krishnas love for Radha-kunda and Srimati Radharani is the same in all respects. Radha-kunda is very rarely attained, even by great personalities fully engaged in devotional service, not to speak of ordinary devotees who are only engaged in the practice of vaidhi bhakti.
It is stated that a devotee will at once develop pure love of Krishna in the wake of the gopis if he once takes a bath in Radha-kunda. Srila Rupa Goswami recommends that even if one cannot live permanently on the banks of Radha-kunda, he should at least take a bath in the lake as many times as possible. This is a most important item in the execution of devotional service. Srila Bhaktivinoda Thakura writes in this connection that Sri Radha-kunda is the most select place for those interested in advancing their devotional service in the wake of the lady friends (sakhis) and confidential serving maids (manjaris) of Srimati Radharani. Living entities who are eager to return home to the transcendental kingdom of God, Goloka Vrndavana, by means of attaining their spiritual bodies (siddha-deha) should live at Radha-kunda, take shelter of the confidential serving maids of Sr Radha and under their direction engage constantly in Her service. This is the most exalted method for those engaged in devotional service under the protection of Sri Caitanya Mahaprabhu. In this connection Srila Bhaktisiddhanta Sarasvati Thakura writes that even great sages and great devotees like Narada and Sanaka do not get an opportunity to come to Radha-kunda to take their baths. What, then, to speak of ordinary devotees? If, by great fortune, one gets an opportunity to come to Radha-kunda and bathe even once, he can develop his transcendental love for Krishna, exactly as the gopis did. It is also recommended that one should live on the banks of Radha-kunda and should be absorbed in the loving service of the Lord. One should bathe there regularly and give up all material conceptions, taking shelter of Sri Radha and Her assistant gopis. If one is thus constantly engaged during his lifetime, after giving up the body he will return back to Godhead to serve Sri Radha in the same way as he contemplated during his life on the banks of Radha-kunda. The conclusion is that to live on the banks of the Radha-kunda and to bathe there daily constitute the highest perfection of devotional service. It is a difficult position to attain, even for great sages and devotees like Narada. Thus there is no limit to the glory of Sri Radha-kunda. By serving Radha-kunda, one can get an opportunity to become an assistant of Srimati Radharani under the eternal guidance of the gopis.”
–Srila Prabhupada (Upadeshamrita Verse 11, Purport)
On the day of Bahulastami, the divine appearance day of Sri Radha-kunda in this world.That is a good day to contemplate the glories of Radha-kunda and of pure devotional service following in the footsteps of the maidservants of Srimati Radharani.
Srila Prabhupada says about Srimati Radharani:
“All glories to Radharani! She is so dear to Krsna. Everyone is trying to love Krsna, but Krsna is trying to love Radha. Just imagine how great She is? Krsna prema is so valuable, but Krsna is after Radharani. She is so great. We have to offer Her our respects”.
“Of all the young girls, Radha is the most beautiful. She always dresses so nicely that Damodara is attracted by Her beauty. If you go to Vrindavan you will find everyone worshiping Radharani. All the devotees in Vrindavan worship Radharani. The pure devotees pray to Radharani, O my worshipable Radharani! You are so full of mercy. I am begging for Your mercy.” (Lecture tape 09/18/69)
