The precious science and wisdom of Yoga have been handed over to us over thousands of years ago. To explore it scientifically from the perspective of the needs of the current generation, it has been my humble desire to study this science with modern inputs so that it is researched again in the light of requirements of the present-recent times. As an essential part of the Integrated Therapeutic Approach called as Sanyukta Upchar Paddhati or Holistic & Integrated Medicine which I have devised and which has been explained by me in this book, I not only studied the science of Yoga but also implemented it in the therapy of the patients whom I treated. Upon this I conclude that Yoga is a boon to mankind, in the sense, the practice of this ancient science confers upon one a strong immune system, it improves health and one's personality, it enhances one's awareness, mindfulness, concentration, memory, mind body coordination, productivity and enthusiasm. It thus helps in combating various diseases that afflict one. It also reduces the daily stress and strain of life. I strongly recommend commencing a Yogic practice and inculcating a Yogic life style right from the young age of life. Of course, Yoga is meant for all, the young as well as the old. This small book provides one with the various aspects of Maharishi Patanjali's Ashtanga Yoga as a part of my Holistic & Integrated Approach of treating patients and also by itself, as a stand alone therapy. May we all benefit from the knowledge dispersed through these pages. Hari Om.
