"The study of Bhagavad Gita would require certain preliminary knowledge. An understanding of the basic concepts of Vedanta philosophy enables one to grasp the deeper imports of the Gita. These concepts were once well known to the average person in the distant past, but with the passage of time they have been lost. They are now well-captured in the commentator's book entitled The Eternities: Vedanta Treatise. A study of the book should be of considerable help to a student launching on an in-depth, meaningful study of Gita."
