Ramanuja (1017–1137 CE) was a Hindu theologian, philosopher, and
scriptural exegete, born in a
Tamil family at Sriperumbudur.
Vaishnavas see him as one of the most important
acharyas (teacher) of their tradition, and as the leading expounder of
Vishishtadvaita, one of the classical interpretations of the
Vedic philosophy. Ramanuja grew up under the tutelage of Tirumalai Nambi, who was working in
Tirumala Venkateswara Temple. Once, a king wanted to punish Ramanuja. Ramanuja's disciple,
Koorathalvar, helped Ramanuja escape and gave him a white cloth to wear. Ramanuja escaped, but the king punished Koorathalvar by blinding his eyes. Following the event, a festival is celebrated in the temple where Ramanuja appears in a white cloth for Koorathalvar. Once, a king took the idol of Narayanapuram to please his daughter. Ramanuja went to Delhi to recover the idol and the idol is believed to have fallen on his lap as a child by divine powers as a child. The Chella Pillai Utsavam is held every year commemorating the event. As per another legend, a king tried to kill a tiger that was trying to attack a cow. In spite of his efforts, the cow was killed by the tiger and the king incurred the curse of the cow. To expiate himself from the sin, he did penance at his place. Adi Kesava is believed to have appeared for the king and relieved his curse. ==Architecture==
