This is not a book about techniques for improving strength or flexibility, performing complicated postures, or climbing huge walls. While both climbing and yoga have undeniable physical benefits, both contribute to a greater purpose: mastery of the mind. A mastery that ultimately serves to achieve and maintain peace of mind. Yoga is a path toward peace of mind that passes through the dissolution of the various layers of the ego that hinder it. It is a path of return, since this peace of mind -it can also be called happiness- is the natural state of the mind, its purest state, free from the alterations that agitate, disturb and pollute it. This path can also be traversed through climbing. Although climbing does not have a philosophical tradition like yoga, in this book you will discover how you can apply several of the precepts of yoga to your work on the rock, turning climbing into a new form of yoga, another path that leads to the same summit.
