The most important benefit of patience consists in the way it acts as a powerful antidote to the affliction of anger - the greatest threat to our inner peace, and therefore our happiness. The mind, or spirit, is not physical, it cannot be touched or harmed directly. Only negative thoughts and emotions can harm it. Therefore, only the corresponding positive quality can protect it.
Every man must patiently bide his time. He must wait -- not in listless idleness but in constant, steady, cheerful endeavors, always willing and fulfilling and accomplishing his task, that when the occasion comes he may be equal to the occasion.
