Saint Goswami Tulsidas (Birth : year 1511, renunciation of the body : year 1623) happened to be a great Saint in Uttar Pradesh. He is known to be the incarnation of Maharshi sage Valmiki. He is the composer of great scriptures like Ramacharitmanas, Ayodhyakand, Sundarkand etc. Let us see an incident in His life highlighting His spiritual authority.
After renouncing His body at His birth place Chitraktut in district Rajapur, Goswami Tulsidas told His devotees in a vision that, I am in an idol form in the river Kalindi (Yamuna), worship Me in a temple. According to this vision, His devotees tried to search for His idol; but in vain. They could not find it despite searching for a week. Hence Tulsidas told His devotees in a vision that wherever you find bubbles in the river, search me there. Thereafter, the devotees found his idol near His house at Prabhu Ghat. The above idol kept in His room where He was born, is that Swayambhu (Naturally manifested) idol.
