After his masterpiece work combining spirituality with mathematics “Law of Love & The Mathematics of Spirituality”, Raju Chidambaram has come out with a wonderful exposition of the “advaita” monistic school of thought in “WHOSE LIFE ARE YOU LIVING?”. In this book he gives lucid account of the non-dualistic treatment of the human soul living in the mortal body with its innate urge to reach the ultimate goal of self-realization at the end of birth and re-birth cycles. Raju is a mathematician by profession and that expertise is evident in the logical arguments and virtual derivation of the sameness of the individual soul with the universal as stated in the mahavakya “tat tvam asi” i.e. “Thou art That”. This book is very strongly recommended for understanding the basics of advaita philosophy. --DR. PRAMOD PATHAK, Author & Indologist, Nashik, India The famous Indian spiritual philosophy of Advaita Vedanta has a reputation for being abstract and esoteric. Fortunately, longtime Chinmaya Mission member Raju Chidambaram has written a congenial and user-friendly introduction, which presents a reliable exposition of the essentials along with some original contributions based on his background in mathematics. The text flows like an intimate conversation with much reference to actual life rather than mere theory. Thus, Vedanta can be put into practice to raise one’s consciousness and achieve greater happiness in life. It is the essence of what is best in the world’s religions and satisfies those who approach spirituality through thought and reflection rather than through feeling and devotion, though the latter can be incorporated as well. This book is a useful and welcome introduction for anyone from any background who is interested in such matters. --BENJAMIN ROOT, Advaitin, Alexandria, VA
