This book is the CLASSIC in terms of breathing & pranayama exercises. It’s a chore to read, though & often contradicts itself in terms of the wild claims it makes around effects & contraindications for various practices.

EVEN WITH all of that, this book will remain on my shelf as an oft-consulted reference (speaks really highly to the contents that I can overlook some of the other major challenges)—I can’t wait until someone writes a modern & well-respected book on Pranayama!!
