Vishnu is considered as alankara priyar (one who prefers decoration), and Shiva as abisheka priyar (one who prefers ablution). Vanamamlai temple is one of the few Vishnu temples where ablution is done for the presiding deity on a daily basis. At around 7 am everyday, ablution is performed on the presiding deity with milk, curd and other pooja items. The ghee used for ablution is poured in the oil well in the temple, which is considered sacred. During the festival occasions, the festival idols are brought to the Vanamamalai Mutt located outside the premises of the temple.
