After the Tiruppavadai Seva, the temple observes some rituals like suddhi (cleaning
of the temple) etc., and the Moola Virat is adorned with Velvet Gown from Crown
to the Feet and then the main deity is decorated with flower garlands. This service
of the main deity being adorned exclusively with garlands is known as Poolangi Seva.
The Poolangi Seva is mentioned in the Silappadikaram, the early Tamil Classic in
756 A.D.
