Ragunatha Dasa Gosvami, one of the six Gosvamis, at a young age renounced his beautiful wife and opulent home to join Lord Caitanya and His sankirtana movement. For sixteen years, he was the personal assistant of Lord Caitanya's secretary, Svarupa Damodara. Along with Svarupa Damodara, he witnessed Lord Caitanya's last days on earth. After the Lord's disappearance he went to Vrndavana, where he lived austerely, absorbed in devotion, in the company of Srila Rupa Gosvami and Srila Sanatana Gosvami.
