This must be gentle, even and deep, and have four stages; (1) pause for preparation, (counting three); (2) breathe in slowly, (counting three; (3) hold breath whilst absorbing life forces, (counting three) and (4) breathe out whilst spreading the new life all over the body (counting three). Then repeat the exercise. As soon as you feel able, increase the counts to four times four and gradually increase until you arc able to breathe to four times seven without strain. (p. 104)

A Yogi, or eastern sage, who wishes to perfect himself begins with the breath, and by its means obtains control over every nerve and function in the body, and finally arrives at super-normal experiences and an ecstasy... Whereas a citizen of Western civilization is usually brought up without any knowledge of the science of breathing whatsoever, his breath being successively restricted by taboos and inhibitions throughout childhood, adolescence, and finally by the anxieties, depressions, bad air and smells, and the nervous rush of modern life. The final result is that the average person hardly breathes at all (compared with what he should do) and therefore is relatively half-conscious most of his days.
