This book is a simplified account of the six systems of Indian Philosophy, also known as the six principal Darshanas. This book is primarily addressed to those who are interested in understanding Indian philosophy in a layman's language. Having said that, it does not mean that, at places, the reading will not become dry and tedious; after all, any philosophical endeavor carries with it such elements. This this book will also appeal to those people of East Indian origin who have adopted the "West" as their permanent home and living in the Western milieu of rationalistic enquiry find it difficult to 'relate' to the Indian religious culture; though, at the same time, they do carry, hidden in their chests, an insatiable curiosity to acquire familiarity with the philosophical roots of their Indian religion. This book will definitely answer some of their questions while raising still many more, which actually is the intention of the author. Knowledge should stay as an on-going process; otherwise, it is likely to become a dead-end ritual. So, grab an easy chair and a cup of coffee and let us get into the atmosphere of Indian philosophy that has prevailed for more than twenty centuries, the atmosphere that still colors the everyday religious life of all Indians, of all ages and of all colors, wherever they happen to be in this world.
