Nand Lal loves the Bhagawad Gita for its universal philosophy and for the simple reason that it has been originally written in Sanskrit. It pains him when one calls Sanskrit defunct. ``It is the source of all our Indian languages. I used to teach philosophy at the Benaras Hindu University and Sanskrit was one of my mains in the IAS examinations,'' he says. Vidur Niti, he says, helps him when he is under tension and Kautilya's Arthashastra is his all-time favourite book. Another book which thisdeeply religious person loves is Aurobindo Ghosh's The Life Divine.
