Yama the God of death and the deity of Sadhya Star worshipped Lord Shiva performing abishek with 1008 conches. These conches have the power of granting longevity. Yama brought the sacred plant Pirandai belonging to the creeper category to earth. He offered rice nivedhana prepared with this pirandai to Lord. This is followed now by devotees for relief from diseases and for longevity. So They also offer Pirandai Rice nivedhana placed on a lotus leaf to Lord and eat it for cure from diseases. We feel blessed.
