From the Body to the Overself. Dewar Adair

Nowadays there are many different forms of hatha yoga, ranging from the extremely strenuous to the very soft.
After many years of personal experience, both through practice and teaching, Dewar Adair, yoga teacher (BDY/EYU) and former aikido instructor, presents a path beyond the mainstream of hatha yoga. In this book he explores to what extent we reduce ourselves and our practice exclusively to the purely physical and asks where the spiritual dimension of hatha yoga is to be found.
He offers answers to these and other questions by taking his readers on a journey away from the body and towards the Overself.
