There comes a time in your martial life when the Master says, “You must now leave this valley of ours, and climb the mountains beyond the horizon”. Sometimes that Master is an actual living, breathing person. Other times that Master lies within you.
No matter. At that time you can only kneel and give one last bow, and then you must leave, never to return.
But you carry the gratitude in your heart, till the end of your days on earth.
Ultimately, that is the Path of every martial artist.
