To get rid of a few problems in general health, to increase one's capacity for work, to make one's character gentler and stronger, to free oneself of various complexes, to create in oneself a whole atmosphere of calm and silence, and to do this by exercises in a gymnastic of repose and by a simple but careful method of breath-control - such aims may appear humble enough, rather down to earth, and a far cry form the goal of even the most modest of yogis. Yet I am certain that they will be able to work real miracles here in the West; to change lives and temperaments completely, making them healthier, more open; to increase their degree of engagement; and to render them more receptive to impulses and promptings from heaven.
