The fundamental aim of all Yogic methods is the diversion of the Prana (breath) which normally circulates in the Ida and Pingala channels into the central Sushumna channel, as was elucidated in a previous post. Numerous yogis across the Indian sub-continent over several centuries perfected a multitude of methods to achieve this common goal. If you ever wanted to read all about it in one place, the “History of Yoga” (editor: Satya Prakash Singh) is for you. This is a massive work comprising 40 chapters spanning about 900 pages written by 19 subject experts which traces the origins and development of Yoga starting from the Vedas to the modern times. It is not possible to do justice to such a large comprehensive volume in a short article. Instead, I will present some interesting tidbits that I gained from the book.
