This austerity commences on the fifth day of the bright half of the Hindu month-kartik and lasts for a year whereby a devotee observes fast on the fifth day (bright half) of the every month that follows. It is related with the worship of lord Vishnu and Sheshnag. A devotee should abstain
from hot and spicy food during the course of this austerity. Lord Vishnu’s idol is purified by chanting mantras and by performing ablution with milk. Offerings of sesame seeds and milk are made in the sacrificial fire. After the accomplishment of the rituals at the year end, brahmins are invited and fed. Finally the idol of Sheshnag is donated to one of them. A devotee who performs this austerity becomes free from all kinds of turbulence in his life and experiences peace and tranquility.
