Each ritual comprises four steps: abhisheka (sacred bath), alangaram (decoration), naivethanam (food offering) and deepa aradanai (waving of lamps) for Viswanathar and Visalakshi. There are weekly rituals like somavaram (Monday) and sukravaram (Friday), fortnightly rituals like pradosham, and monthly festivals like amavasai (new moon day), kiruthigai, pournami (full moon day) and sathurthi.
