A person who undergoes the Kalpavãsa Vrat is honoured with the title of Kalpavãsi

A unique feature of the Indian Bathing Festivals - Kumbha (Kumbh) Mela, Magha Mela, Etc. is that of the Kalpavãsis, who present a scene of Vãnaprasthãshrama Dharma (retired forest life prescribed in the Vedas for couples). The Kalpavãsis spend the Kumbha (Kumbh) Mela living an austere and minimalistic life

Most of them stay in thatched huts, sleep on sandy river beds, listen to discourses, assimilate the essence of Dharma and give alms. Some of them bathe in the holy river thrice daily and eat only once
