Answer: This is a science in itself. We are far away from a natural life. We have to run after tram-cars and taxicabs, we have to catch our trains; a thousand things like these disturb our rhythm. Do you think that in the East a sage, or an adept who practices meditation will run after a tram-car and spoil his rhythm? All these things disturb the rhythm of breathing. What we think natural is not natural; from morning to evening our life has no rhythm.
