Be the master of your mind rather than mastered by it.
"I can't go on.
Whatever state of mind has you calm, centered, quiet, and aware - this should be your mental posture.
Whether you are in motion or at rest, maintain your mental posture at all times, steady as she goes, regardless of the task at hand. The ineffable teaching of all teachings resides within this. -md
