Encyclopaedia of Vedic Philosophy
by P.R.P. Sharma

Contrary to the popular perception that Indian civilization has been largely concerned with the affairs of the spirit and "after-life", India's historical record suggests that some of the greatest Indian minds were much more concerned with developing philosophical paradigms that were grounded in reality. 

This book is an introduction to Vedic philosophy.  It is introductory in two ways. First, it presupposes, on the part of its readers, no prior acquaintance with the subject.  It should be capable of being understood without any such acquintance. Second, it begins, not with the discussion of particulars problems, but with an account of the general nature of philosophy.
