1) Kumbabhisegam / Samprokshanam:
Kumbabhisegam has to be performed for every temple once in 12 years according to the agamas (to perform 'Ashtabandana Kumbabishegam' for Moolasthana moorthy which are without/aged and poor ashtabandana marundhu). Samprokshanam is the word used for vaisnavite shrines. Water is springled or sprayed to Moolasthana moorthy and kalasams on the tower in vaisnavite shrines.
So after 12 years Kumbabhisegam was due in 2004.
Kumbabishekam recharges the spiritual power of the deity and also the Kumba of the temple tower, which is also surcharged with the same divine power as the deity. This is done to benefit even those who are unable to visit the temple derive the same spiritual merit by just beholding the temple tower.
2) Kumbabishekam of rich temples:
There are more than 150 temples with annual income of more than 10 lakhs. Temples like Tiruttani, Palani, Srirangam, Thiruchendur, Madurai Meenakshi, etc will easily collect more than 10 crore each every year. Even in these temples Kumbabhisegam are not performed once in 12 years.
3) Monetary Constraints:
What is the fate of about more than 38,000 temples in Tamilnadu for conducting Kumbabishekam once in 12 years? The fact is many temples find it difficult even to do daily poojas. Government alone can not do this job. Only well wishers, followers, beneficiaries and bhaktas may take up this work locally.
