In July 1962, Bhaktivedanta Swami moved to Radha Damodara temple in Vrindavana. It was a small room, 7x15 feet, with smooth plastered walls and floor of uneven sandstone squares. Without moving from his room, he could look into the temple and see a portion of the altar. He could also see the black marble Deity of Vrindavanachandra that Krishnadasa Kaviraja had worshipped hundreds of years ago.
