Sri Sri Raghavendra Swamiji

Sri Sri Vishvesha Theertha Swamiji

Sri Sri Vishwesha Theertha Swamiji was born on the 27th of April, 1931 as the second child of Sri Narayanacharya and Srimati Kamalamma, a devout couple from Ramakunja. The parents named the child as Venkataramana. Hugely impressed by the Satvik nature of the young Venkataramana, the then head of the Pejavara Matha, Sri Sri Vishva Manya Theertha Swamiji initiated him as a Sanyasi when he was in his 8th year of age! The initiation happened on the 3rd of December 1938 at Chakratheertha, near Hampi. Upon initiation, Venkataramana became Sri Sri Vishwesha Theertha. The early education of the young Sanyasi happened at Udupi itself. The head of the Bhandarakeri Matha, Sri Sri Vidyamanya Theertha Swamiji, taught all the Shastras to the young Yati for eight years and helped transform him into a knowledgeable and erudite scholar of Vedanta and Shastras. Sri Swamiji quickly became an extraordinary scholar in Nyaya, Vedanta and other branches of philosophy.
