Bhagavad-gita constitutes divine instructions that are recorded in the Bhisma-parva of the Mahabharat (also known as the pancama-veda). It is the essence of all knowledge, spoken on this planet for the guidance of mankind & is hence extremely popular. Inspite of being the most widely read philosophical treatise, it has remained a mystery for most people & one may wonder why this is so. This book contains notes that we hope will unravel this great mystery & enable a reader to dive deep into the esoteric message of the Gita, and practically apply its teachings in everyday life - in such a way that life can become ever fresh, meaningful and joyful.
