People who become impulsive, or show irritability in nature, who become impatient at times, who get fits of anger, passion, or laughter, who get spells of tears - all have an irregularity of breathing, which is the cause of all this. The physician has no remedy for their ills; modern psychology has not found the link; but the mystics from of old have for years believed - and not only believed but practiced - and have found in the end that balance of mind entirely depends upon regularity of breathing.
