Radha Kunda (well) is known to be the sacred bathing place of Radharani. She had rebuked Krishna, saying that he became impure by killing a bull, the symbol of religion. She suggested that he could purify himself by taking bath in all holy rivers.
Rather than travelling to all sacred places, he struck the ground with his heel and water from all holy rivers appeared. The place was then known as Shyama-kunda. In a competitive mood, the Gopis led by Radharani also created a kunda by digging the earth with their bangles. Thus, Radha kunda appeared.
