Yoga is a pride possession of our great Indian tradition. Yog knowledge can offer the lightest goal and bliss of life. An anthology of the discourses were expounded by Prashant Iyengar which have been presented here in a book form. Pranayama is a compound word meaning Prana 'Vital Energy' and Ayama 'Control and Regulation'. But it is not basically breath-control or breath-regulation. Pranayama needs a lot of study of breath usages, applications and Addressals by-on-in-with breath. Pranayama is the vital energy, which apparently distinguishes animate and inanimate or living and non-living creation. The animate things are believed to be breathing is characteristic to the bio-world or living creations. This breath oscillation in human beings signifies the existence of Prana in the embodiment. The departure of Prana marks the end of re-spiration and death of the living being. This book provides a classical and traditional approach towards life by breath control with different type of asnas. This differentiates between physiology of respiration that comes in body-science and physiology of breathing that occurs in the science of yog. According to the book the entire human embodiment is a breathing organism, even inner, outer, physical, psycho-mental, psychic, gross and subtle and esoteric organs, senses and constitutions.
