The deity of Lord Venkateswara at Tirupati-Tirumala is a form of Lord Vishnu. He is also called Balaji, Srinivasa and Venkatachalapati. It is said that Vishnu appears on earth whenever evil is on the rise and humanity needs to be saved. Lord Venkateswara has thus appeared in the Kali Yuga to offer salvation to humanity and his name means ‘the lord who destroys the sins of people’. Thus the temple at Tirumala is considered his heaven on earth, a Kaliyuga Vaikuntham.
