Shri Hira Ballabh Joshi has been working towards establishment of a reformed, accessible, inclusive and economically viable Vriti (priestly profession) which is easily acceptable to the present society. He believes that the priestly function is like a nervous system of Sanatan - Hindu Dharma. Therefore, it needs to be given a due recognition in the society. Shri Joshi, a senior officer of Civil Services, hails from a family of Purohits and has extensively written on the Dharma Traditions of Bharat-varsha. The present edition is a revised version aimed for the use of priestly class as well as for the general public. The Introduction deliberates on various aspects of Sanatan Dharma so as to make the subject easy to grasp.
