As the mechanism of the body depends upon the breath for its subsistence as well as for its health, so the breath is important in sustaining the mind and keeping its work regular. Mostly confusion, depression, or any other disorder of the mind arises from the disorder of breathing. All such diseases as hallucinations and delusions are caused by wrong breathing. For instance, if a person comes running or is hurried for a moment, he loses the regularity of his breath for that moment, and at that moment he is incapable of thinking rightly.
