Kalpavãsa VratÂ

A day’s stay (Ahoratra) in the world of Brahma is known as Kalpavãsa. This is impossible in the human form. Under the circumstances, lest, us humans should remain deprived of the benefits of Kalpavãsa of the Brahmaloka, there is provision for us at the Kumbha (Kumbh) Mela, Magha Mela, Etc. where we can get the same fruits, reap the same benefits, experience the same as may be attained through the Kalpavãsa of Brahmaloka
