According to the science of rituals, rites such as til?njali and pin?ad?n (Ritual of offering of rice balls) should be performed beginning from 1st day till the 10th day. Visham shr?ddha should be performed on odd days. If that is not possible then uttar-kriyashould begin from at least the ninth day. Nowadays, however, pin?ad?n that should be performed from 1st day to 10th day is performed as a combined ritual on the 10th day. On 10th day, pin?ad?n is performed in a Shiva temple or in a temple of an inferior Deity situated on the bank of a river.
After the pin?ad?n on the 10th day, a little coconut oil is poured on the ashma and it is immersed in flowing water.
