Every Friday after Suprabhatha Seva, the regular Thomala and Archana Sevas are done in privacy and then Srivari Abhishekam is observed. This happens to be the most ancient Arjitha Seva that is being observed in the hill shrine of Lord Venkateswara.
The Abhishekam starts with Sacred water brought from Akasa Ganga Theertham, then with Milk, then with Suddhodakam, Chandanam and other scented articles like powdered Pachcha Karpooram, Saffron paste and drops of civet oil etc., which are brought earlier in the silver vessels.
While performing the Abhishekam to the Moola Virat, Purshasukta, Narayanasukta, Srisukta, Bhusuktha, Neelasuktha and selected Pasurams from the Divya Pradbandham are all recited by the priests. Later, the Abhishekam is performed for the image of Goddess Lakshmi on his chest with Turmeric Paste.
The Arjitha Grihastas who take part in this seva, are all assembled inside the temple and each one is entrusted with one Silver Vessel that contain various scented articles like powedered Pachcha Karpooram, Saffron paste, drops of civet oil, Chandanam and etc.,
All the Arjitha Sevaparas carry these articles round the inner prakara of the temple accompanied by Mangala Vayidyas. When they reach the Bangaru Vakili, the vessels and plates are collected by the Archakas and the contents will be used while performing Abhishekam to the Main Deity.
In the year 966A.D. a Pallava Queen “Samaavai" gifted the present silver idol of Bhoga Sinivasa Murthy to the temple. This idol is exact miniature replica of the main vigraha. The year when she gifted, it was on Jyestha Bahula Tritheeya when Sravana star was in the ascendant in Akshya Year and it was on Friday.
While installing the Bhoga Srinivasa Murthy idol in the Sanctum, an Abhishekam was performed to the main deity also. Thus, started the practice of doing Abhishekam to Moola Virat on every Friday
