A wandering mind leads to dissatisfaction. This unpleasant state can be overcome by applying a disciplined approach to every experience. DO NOT LET THE MIND WANDER! It will crash and produce pain.
You don’t have the luxury of letting your guard down. You must take the wheel and steer the ENTIRE time. Eating, thinking, working, talking, reading, watching – ALL things must be done in a state of awareness.
Focus defines existence. A wandering mind focuses on whatever – eventually arriving at something unpleasant. Through discipline, the mind should be directed to a decent destination.
As the Buddha said:
Suffering exists. It is the result of wanting. Suffering ends when wanting ends. End wanting by remaining aware and properly focused.
