Lord Caitanya was searching for Aritagram, because according to the scriptures this is the place where the famous Radha-Kunda and Shyama Kund were present. So one day Lord Caitanya sat under a Tamala tree and while meditating upon Radha-Kunda and Shyama- Kunda, He saw two bodies of water in a nearby paddy field. Lord Caitanya who is none other then Radha and Krishna, could immediately identify them as Radha Kunda & Shyama Kunda. He very happily took the waters of the kundas and applied tilaka on His body using the clay from Radha-kunda.

Sanatana Goswami instructed him to stay near Radha-Kunda where he daily spoke for 3 hours on Gaur Lila. He performed his bhajan at Radha-Kunda. One time Raghunath Das Goswami, understanding the mood of Lord Chaitanya, was thinking that Lord Caitanya wanted the holy places of Vrindavan to be excavated for the benefit of all people. But at that time Radha-Kunda & Shyama-Kunda were just two small ponds. Raghunath Das Goswami thought of excavating them but he didn’t want to entangle himself in money etc. Radha & Krishna understood his heart.
At the same time a wealthy merchant was on his way to Badrikasrama with the intention of building a beautiful temple for Lord Badrinath. Badrinath appeared in the dream of that merchant and instructed him to excavate Radha-Kunda under the guidance of Raghunath Das Goswami instead. In this way Radha-Kunda & Shyama-Kunda were excavated.
