The PROUT Companion is an edited version of PROUT Giita, the 1978 handbook written by Acarya Raghunath Prasad. The original diminutive, pocket-sized book
supplied Proutists with a comprehensive review of the ideological basis, fundamental principle of Prout, as well as core philosophical and scientific perspectives.
In 2010, the original text was edited and updated, and the work was given a more universally applicable title. Hereby a new generation of proutists have the opportunity to experience and learn from the significant contribution of Acarya Raghunath, an early and learned proutist who used to receive information and teachings directly from Shrii Prabhat Rainjan Sarkar, the propounder of Prout.
