| When the Brijbasis heard that Krsna killed Aristasura they all rushed to the spot; Srimati Radharani and Her sahkis came as well, but upon hearing that Krsna had killed a bull, became very upset and told Him that They would no longer associate with Him due to His sinful act of killing a bull. Krsna pleaded with Srimati Radharani that since Aristasura was not really a bull, but a demon disguised as a bull, there was no sin in killing him. Srimati Radharani would not accept this, and told Her beloved Krsna that in order to have Her association, He would have to become purified from killing a bull, and to do so, He would have to take bath in all the holy places of the universe. She explained that only then would She associate with Him again.
Krsna agreed to Srimati Radharani's proposal, and told Her that instead of having to leave Vrndavan to travel to all the holy places in the universe to take bath, He would instead call all the holy places in the universe to come to Vrindavana, and then take bath there. Thus, striking His heel into the ground, Krsna made a very large hole and called the predominating Deities of all the holy rivers of the universe to come to Him. One by one all them came in their personified forms and offered their prayers to Krsna Who then ordered them to pour their sacred waters in to the newly made kunda which they filled it up. To please Srimati Radharani, Krsna took His bath in the newly formed (Syama) kunda, which is still known by this name.
Krsna then began teasing Srimati Radharani and Her sakhis saying that because they were only simple village girls they must have never performed any kinds of sacrifices to please the devatas, that for them to side with a demon (Aristasura), they were impious, that this was sinful, and thus, they must undergo some form of purification. Krsna explained that in order to relieve themselves from such a sin they must, like Him, also take bath to purify themselves.
Srimati Radharani deciding not to allow Krsna to get the better of Her and Her sakhis, accepted what Krsna said, and decided that She would create a kunda just as good or better than that which Krsna had made. Thus, Srimati Radharani broke one of Her bangles, using it as a digging instrument, and began to dig out the soft earth with it. Seeing this, the other gopis also broke their bangles and started digging. Within a short time a large kunda had been created right next to kunda Krsna had created.
Krishna was amazed to see the large hole that Srimati Radharani and Her sakhis had created. Krsna offered to allow the waters from His kunda to enter into Hers, but Srimati Radharani refused Krsna's proposal saying that the waters of Syama kunda were contaminated due to the sin of cow killing. She said that Her sakhis would form a line from that place and bring the pure waters of the Manasi ganga in golden pots to fill Her kunda.
Upon hearing Srimati Radharani's words, the holy places personified came to Her, and with folded hands chanted beautiful prayers in glorification of Srimati Radharani and asked if She would allow them the mercy to be able to pour their sacred waters into Her kunda also. While glancing at Her beloved Syamasundara, Srimati Radharani mercifully and happily agreed to their proposal. In joyous mood, the holy places personified brought their waters by forcibly breaking through the banks of Syamakunda and entered into Radha kunda.
Krsna then immediately took bath in Radhakunda and declared that from that day forward, anyone who with firm faith took a bath in Radha-kunda, would achieve the same ecstatic love that Srimati Radharani had for Him. Radharani and Her sakhis then took bath in Syamakunda. Srimati Radharani declared that anyone who takes a bath in Syamakunda would achieve the same ecstatic love that Krsna has for Her.
Here's a little extra from Srila Rupa Goswami's Upadesamrta:
"The holy place known as Mathura is spiritually superior to Vaikuntha, the transcendental world, because the Lord appeared there, Superior to Mathurapuri is the transcendental forest of Vrindavana because of Krishna's rasa-lila pastimes. And superior to the forest of Vrindavana is Govardhana Hill, for it was raised by the divine hand of Sri Krishna and the site of His various loving pastimes. And, above all, the super-excellent Sri Radha-kunda stands supreme, for it is over-flooded with the ambrosial nectarean prema of the Lord of Gokula, Sri Krishna. Where, then, is that intelligent person who is unwilling to serve this divine Radha-kunda, which is situated at the foot of Govardhana Hill?"
Part of verse #10
"The gopis are exalted above all the advanced devotees because they are always totally dependent upon Sri Krsna, the transcendental cowherd boy. Among the gopis, Srimati Radharani is the most dear to Krsna. Her kunda [lake] is as profoundly dear to Lord Krsna as this most beloved of the gopis."
From Srila Prabhupada's purport:
"Thus of all the devotees who have developed unalloyed devotional love for Krsna, the gopis are most exalted, and out of all these exalted gopis, Srimati Radharani is the highest. No one can excel the devotional service of Srimati Radharani. Indeed, even Krsna cannot understand the attitude of Srimati Radharani; therefore He took Her position and appeared as Sri Caitanya Mahaprabhu, just to understand Her transcendental feelings.
"In this way Srila Rupa Gosvami gradually concludes that Srimati Radharani is the most exalted devotee of Krsna and that Her kunda (lake), Sri Radha-kunda, is the most exalted place. This is verified in a quotation from Laghu-bhagavatamrta (Uttara-khanda 45), as quoted in Caitanya-caritamrta:
yatha radha priya visnos tasyah kundam priyam tatha sarva-gopisu saivaika visnor atyanta-vallabha
"Just as Srimati Radharani is dear to the Supreme Lord Krsna, so Her bathing place (Radha-kunda) is equally dear to Krsna. Among all the gopis, She alone stands supreme as the Lord's most beloved."
"Of the many objects of favored delight and of all the lovable damsels of Vrajabhumi, Srimati Radharani is certainly the most treasured object of Krsna'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 Krsna is fully aroused."
Srila Prabhupada's purport:
"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 Krsna. 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 Krsna as Radha Herself. Indeed, Krsna's 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 Krsna in the wake of the gopis if he once takes a bath in Radha-kunda. Srila Rupa Gosvami 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 Sri 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 Krsna, 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."
