Sage Patanjali systematized the science of Yoga that has been in existence in India since times immemorial. Historians believe that he lived near Lucknow in Uttar Pradesh in BC 400. So the Yoga Sutras are about 2400 years old.

He built the edifice of his Yoga Sutras on the foundation of a much older Sankhya philosophy. In this course he appears to have borrowed some concepts from Buddhist philosophy also. Sage Vyasa, King Bhoja, Adi Sankara, Vachasapati Misra, Vijnana Bhikshu, Ramananda Saraswati were the main commentators on these highly abstruse sutras. In the modern age, Swami Vivekananda breathed new life into them by his English speeches some 125 years back. I made a humble attempt to explain the intricacies of these sutras in a simple manner. I believe this book will make the reader understand the real meanings of the sutras in a simple and straight manner.
