Born as Muddu Krishnacharya, he seems to have studied tarka (Logic), vyakarana (grammar) and mimamsa (scriptural injunctions) under the guidance of Raghavendra though he considers his father, Venkatanarayana, as his teacher. His two brothers Yogindra and Surindra served as pontiffs of the matha before him. He took on the name of Sumatindra after his initiation into sannyasa. Through his travels in the present day Karnataka and Telangana, he engaged in debates and discussions with Advaita and Dvaita scholars alike. He maintained cordial relationship with the Madurai Nayaks and the Thanjavur Marathas as evidenced by grants made in his name. Queen Mangamma of Madurai granted him the hamlet of Ayirdharma and lands in the town of Srirangam where he built his matha. Under his aegis, the matha also received a part of the tithes from Payaranipalyam and other neighboring villages. His panegyric on the Thanjavur ruler Sahaji I indicates familiarity with the ruler. Succeeded by Upendra Tirtha, he is entombed in Srirangam.
