Swami Mudaliyaandaan was born in 1027 CE at Pachhai Vaarana Perumal Sannidhi (referred to as "Nazarethpettai" today) in Thondai mandalam, in the state of Tamil Nadu in South India.
[citation needed] Having begun his learning with his father, Daasarathi would go on to become, with Koorathazhwan, a pillar of support to Emberumaanar, acclaimed by him as being identical to his thridandam - his staff of office as a sanyasi.
He was later to be known as "Sriranganaatha Divyaalaya Nirvahana Dhurandhara" - the genius who organized, under Emberumanaars tutelage, the administration of the Sri Ranganathaswamy Temple.
