Once a scholar of Ramayana Shri Umayalpuram Vengu bhagavathar came to Thiruvaiyar for giving discourse on Ramayana for stretch of six months. Thyagaraja attended those discourses and appreciated Vengu Bhagvathar.   Then Vengu bhagavathar requested Thyagaraja for teaching music to his young brothers Kishnan and Sundaram. He accepted them as students. However, he made a practice that the fresh students would first be sent to Jagadrashaka bhagavathar in Aditurai for around 6 months for learned basic music till varnams. Umayalpuram brothers followed the same regime and joined Thyagaraja in due course. Later they became repositories of hundreds of compositions of Thyagaraja
