Tirumala Hill is a vast area with many peaks from which lakes & waterfalls rises. Of these, 108 are believed to be sacred and associated with various epic characters and miracles of Lord Venkateswara.
The Swami Pushkarini belonged to Vishnu in Vaikuntam, and was brought to the Earth by Garuda for Vishnu's sport. On the western bank of the Swami Pushkarini is
Sri Varahaswami's temple, while on its southern bank is
Sri Venkateswara swamy temple. It is the sacred tank, even regarded as equivalent to the Ganga and other sacred rivers. A dip in the tank, cleanses the bather of all sins. The performance of the daily rites or even occasional rites on the banks of the Swamy Pushkarini is said to cure deformities of the body and ensure the avoidance of all types of hell. It grants the wishes of those who bathe in it. Like the Hill, all the tanks and lakes of Tirumala are sacred and known as Theerthas. There are 17 theerthas whose Holy waters are believed to mingle in the Swami Pushkarini to wash off their sins.
The sacred Mukkoti or parva dina of the Swami Pushkarini takes place on Dvadashi in the month of
Dhanurmasam (dec-Jan) when Vishnu's chakra is taken in procession and immersed in the Swami Pushkarini, when all the Gods bathe in the tank. A bath at the same time, washes all the sins. It is believed that all the sacred waters including
Ganga, merge in Swami Pushkarini once in a year.
The wooden-float festival of Lord Sri Venkateswara in the month of February/March and
Avabhrudhasnanam or Chakrasnanam during
Brahmotsavam takes place in the
Swami Pushkarini.
