Akasa Ganga Teertham is located 4kms from the main temple on the way to Papavinasanam. According to the legend, Akasha Ganga theertham has originated from the lotus feet of Lord Venkateswara. All the rituals of the temple including Abhishekam are conducted with its waters.
It is believed that Akasaganga Teertham has the powers to cleanse evils and bring good luck to everyone who takes a dip in its water.
History & Origin of Akashaganga
A great Vaishnava Acharya, Peria Tirumalanambi (973 AD) was performing services to Lord Venkatewara by bringing water from Papavinasanam falls for the daily morning pooja of the Lord. Even during his old age, he was doing the service to Lord. The Lord out of mercy took the form of a Fowler (hunter) and stood before the Acharya begging for the water to quench his thirst, Acharya refused to give water to the fowler as the water is to be offered to Lord Venkateswara pooja.
While Acharya was moving away with the water pot, the fowler shot arrow at the pot and drank the water from it. Acharya Tirumalanambi felt sad for the act of the Fowler and started going back to bring the water. Then the Fowler addressed Acharya, “THAATA ! Don’t Worry” I will make a place near the temple to bring the water another new falls. He struck the spot in Anjanadri Hill with his arrow and the sacred water gushed out from the hillock.
The Fowler appeared in the form of Lord Venkateswara and told Acharya Tirumalanambi to bring sacred water for his Aradhanam from Akashaganga only. Even today the descendants of Acharya Tirumalanambi are doing the rituals.
