"Sakshi-gopala" is a collection of essays describing bhakti-yoga, the science of self-realization, and Krishna consciousness based off select verses from sacred Vedic texts like Bhagavad-gita, Ramayana, Chaitanya Charitamrita, and others. Estimated length of 264 pages.
"The Lord heard the story of Sakshi-gopala with great pleasure because He wanted to impress upon the atheists that the worshipable Deities in the temples approved by the great acharyas are not idols, as alleged by men with a poor fund of knowledge." (Shrila Prabhupada, Shrimad Bhagavatam, Introduction)
