In Bengal, there was a brahmana named Krishnadasa. He knew the Vedanta and had subdued all his senses. He visited many places and had a pilgrimage to all the holy teerthas and finally reached Shri Brindavan that bears the holy imprint of the holy feet of Shri Radha Devi. He led a peaceful and happy life daily reciting the Bhagavatam and worshipping Lord Krishna, always remaining in the company of the sadhus.
