It is through the breath that birds receive warnings of the changes of the weather, and accordingly they migrate in flocks from one place to another. Through the breath the herds of deer perceive approaching storms or changes of weather or the approach of a lion or a tiger. Man, who is more capable of perceiving by breath still deeper things, warnings and calls from the earth and from heaven, which places are meant for him to dwell in or to settle in, of discriminating between friend and foe and discerning their pleasure and displeasure, owing to his interest in the superficial things of life cannot fully benefit by the power of breath.
