This book represents an endeavour to demystify the glorious heritage of Yoga. It is a concise but lucid "manual" of Yoga Sadhana that encompasses the conceptual as well as the practical elements of this universal art, science and technology of living. The first section of the book presents a simple but profound framework that communicates the essence of the Samatvam Yoga path. It makes Yoga practice and sadhana intelligible, even to the lay person. The second section explores the nature of the universe as well as the human being. The third section lays out the four pre-requisites for meaningful Yoga practice, by way of appropriate food and diet, lifestyle, attitudes and perspectives. The fourth section of the book explains the foundations of Yoga sadhana, by way of Yama and Niyama. The fifth section explicates the techniques of Asana Pranayama and Pratyahara in considerable detail. The last section deals with the actual sum and substance of Yoga, by way of Dharana, Dhyana and Samadhi.
