Recently Eddie Stern wrote a book " One Simple Thing". That book is literally "must read" for all yogis and science enthusiasts. Eddie covers different topics in the book: what is yoga, ashtanga yoga from ancient sources, benefits of yoga postures, yoga and nervous system, awareness during asana practice, mind and body connection and the like. Tremendous knowledge and deep perception of true yoga, and scientific approach made that book a real treasure for physical and mental health seekers.
