Sri Radharamana's lotus face is like Sri Govindaji's, His chest is like Sri Gopinath's and His lotus feet are like Sri Madanmohanji's. By taking darsan of Radharaman one receives the simultaneous darsan of these three primary Deities of Vrindavan.
The Deity of Sri Radharaman was manifested from one of Gopal Bhatta Goswami's salagram-silas on the full moon day of Vaisakha (April/May) in 1542.
This event is celebrated every year (May) by bathing the Deity with 100 liters of milk and other auspicious items. Gopal Bhatta Goswami's other salagram-silas are also worshiped on the altar. There is no Deity of Radharani with Radharaman, but gomati-cakra is worshipped on the altar to His left. According to an injunction of Sri Hari-bhakti-vilas, a gomati-cakra is to be worshipped along with a salagram-sila.
Before large temples were built, the Goswamis worshiped their Deities simply, keeping them in a tree under which they slept. Radha-raman Deity was adored in a tree for centuries. In the area of the present Radha-raman temple, there used to be a large lake, connected to the Yamuna river......For a couple of hundred years they worshiped Radha-raman in a tree, and at night put him in a boat anchored in the middle of a lake.They stood guard with bows and arrows, if anyone came to hassle the Deity. Even today, they have the bows and arrows in the temple.
One rich businessman made an offering of clothes crowns, and jewllery to Srila Gopal Bhatta Goswami, who lamented that, as he was worshipping Sri Shaligram which was round just like a stone he could not dress, or put crowns and jewellery like the other Goswamis were doing with their Deities.
Lamenting in this way, the Goswami took rest. Early the next morning when he came to offer the seva arpanam puja for the Shaligrams he discovered that one of the Silas (Damodar) had transformed into the most beautiful three fold bending Deity of Krishna, Who had manifested Himself out of love, just to receive loving worship from Gopal Bhatta Goswami. The name Radha Raman means "one who gives pleasure to Srimati Radharani". This is one of the numerous names of Lord Sri Krishna. There is no external manifestation or Deity of Srimati Radharani in the temple but there is a crown next to Ramanji that represents Her presence.
Gopal Bhatta Goswami was the son of Vyenkatta Bhatta, a brahmana priest of Srirangam Temple in Tamil Nadu. In 1511 Sri Chaitanya Mahaprabhu visited Srirangam a danced in ecstasy before Lord Ranganath.Vyenkata Bhatta invited Lord Chaitanya to stay at his house during Chaturmasya in Sri Rangam. Gopal Bhatta was at that time small boy and got the chance to serve the Lord and hear directly from Him. After some time Lord Chaitanya left on his tour to South India and told Gopal Bhatta to go in the future to Vrindavan...
Gopal Bhatta became learned in Sanskrit, poetry, rhetoric and all aspects of devotional service. After passing of his parents, he left home and proceeded towards Vrindavan where he joined Rupa and Sanatan...
After some time studying in Vrindavan Gopal Bhatta made a trip to Nepal. One day when he was taking bath in Kali-Gandakini river, he dipped his kamandalu into the water and 12 silas mysteriously entered his water pot...
He put them back into the water and dipped the kamandalu again in the water of the holy river, but the silas again entered his water pot.
When it happened for the third time, Gopal Bhatta realized, that those are not ordinary stones, but they must be some very special ones and there must be some divine arrangement behind it. He kept them in a cloth bag hung around his neck and from that time on he started to worship them and then returned to Vrindavan.
As previously mentioned, once he intensely desired to decorate his salagram as the other Goswamis could decorated their Deities, then seat Him on a swing and serve Him as other devotees can. "If only He had arms and legs like a Deity," he thought.
Lord Krisna, being very kind to His devotees, that very night transformed Himself from one of small salagram-sila into threefold form of Radharaman. If one has darsan of Radharaman's back, one will see that it resemble salagram-sila. Although the Deity is quite small many devotees find Him to be extremely attractive.
