Tirupati Balaji - A Sacred Tank for Abhishegam water
The worship of Lord Balaji is done as Mother Goddess (Ambal) for 4 days, as Lord Maha Vishnu for 2 days and as Lord Siva for one day in a week.
The Abhishegam water / liquids are let out through a pipe into the nearby sacred tank of the Temple called Pushkarani. Hence the water in the tank is also considered to be sacred (Even otherwise all temple tanks are considered as sacred waters capable of removing one’s sins on taking a dip) After taking bath in the temple tank the devotees offer Arghyams - lift the water in the palms keeping both hands as a pouch to the Lord but the water is allowed to be let into the tank itself. This is also considered to be one type of worship.
A Special Worship on Fridays
On all Fridays in the early morning, a special worship is performed before the commencement of Abhishegam. One sloka in Tamil beginning with the words "Venkatam Yenap petra and a Thaniyan individual compilation) are sung in the Vadakalai Sampradhyam, one of the Vaishnava Sects.
During this special worship the Idol is without any dress or flower decorations. Camphor is lighted and shown to the Lord as Arathi. Then the worship in the Thenkalai Sampradhayam is performed. Then Neivedhyam is offered to the Lord. Once again a karpoora arathi is performed. The idol of Lord Balaji at that time would be shining beautifully and is a treat to the eyes.
The flower garland worn by the idol of female devotee known as Sri Aandaal at Srivilliputhur temple of Tamil Nadu is brought daily to the Hills and offered to Lord Balaji.
