In Hinduism Lord Venkateswara is the Supreme God also another form of Lord Vishnu. In this KaliYuga people are attached themself to material pleasures and forgot the diveness and so yogies praied Lord Vishnu ,should appear in Kaliyug to destroy the sins of the people,and develop self-realization, so he incarnated as Lord Venkateswarsa (which means Supre God destroys all the sins) from his devotees wishes. The other names for Venkateswara are Srinivasa, Venkatachalapathi, Balaji, Narayana, Narayanadhri , Tirupathi Timmappa also. The Lord Venkateswara is appeared to be on seven hills(Venkata Hills) which is now populared as Tirumala near Tirupathi. That’s why he is also refered as “Yedukondala Venkateswara” (Seven hills recieted God) also by his disciples. Padmavathi is at her foot down called as Tiruchanur (Tirupathi)
