Anyone who has ever been sincerely interested in Hinduism, Vedanta or the general philosophy that has come out of India needs to read this book. Or if you are looking to deepen your practice, this is a wonderful treatise to read and think a lot over. While it is not a primary source, I’d say it is best to start with something like this because it gives a beautiful, comprehensive and lucid overview of the subject. At the same time, this isn’t a summarized superficial stab at this complex subject. It digs deep, and nuances of meaning are brought forth in a pure manner.
