Kumbabhishekam, Samprokshanam, Ashtabandhanam, Jeernodhaaranam are all phrases we hear about the spiritual rejuvenation of Hindu temples periodically-usually once in 12 years.
Ashtabandhanam is the process of reinstalling the murtis with the ashtabandhana mixture. This is a combination of eight or more ingredients, including, wood lac (arakku) , red ochre (kaavi), limestone, rosin, beeswax, and butter.
The picture shows the pounding (in ‘ural’ with ‘ulakkai’) and blending of the ingredients at Sree Kapaliswarara temple a day before the Kumbabhishekam. You can see the finished mixture and dollops of butter on the floor and the semi-finished mixture in the ural.
