During Kumbabishekam period, Balayalam is done in a Hindu Temple. To be precise, the divine
power of the main Deity along with other Deities of the Temple are transferred to a Kalasha.
The Kalasha is placed atop the Balalayam. It means a mini Aalayam. This is specifically done
during the renovation period of a temple. Since the divine presence of the Main Deities are
transferred to the holy waters contained in the Kalasha, puja is done to the Kalashas and
Ustava Vigrahams of the Temple. During this period, no puja will be performed to the Moola
Vigrahams. The divine presence of the temple deity will continue to be in the Kalashas
only until it is transferred back to the Moola vigrahas, on the day of Kumbabishekam.
