When Appar (also known as Thirunavukkarsar) visited Pazhayarai (Vadathali - in the 6 - 7 Centuries), that temple was covered by Jains and Appar had to use local influence to clear the temple for worship. He also found several other temples covered by trees, creepers and Putrus.. For this, he used a tool which is similar to our "Dosai Thiruppi". We have seen SivajiGanesan with this in Thiruvarutchelvar. This is known as UZHAVARAM. The work force is UZHAVARAPADAI. Temples which are not frequently visited are frequently covered by grass etc. Local Youth Missions are established under the name of UZHAVARAPPADAI to clean the temples. Of late, this SRAMA DHAN (Donating Physical Labour) has picked up even in crowded temples. Prior to Vaikunda Ekadasi, recently in Srirangam Temple, I have seen very rich persons - men and women (including North Indians) cleaning the oily surfaces of various walls and pillars around the sanctum. I also took part for a while. We were all supplied Uzhavaram!
