Here is an excerpt from Great Grandmaster Tae Yun Kim‘s book, The Silent Master:
Here’s a story of an Old Man and a Baby that illustrates what I mean.
During a war, a group of people were fleeing from the enemy. Among them was an old man and a woman with a baby. For many days they ran and hid, always with the enemy close behind and danger from every corner.
As they ran, others in the group helped the mother carry the baby, except for the old man who was already very weak.
After a few days the old man was so tired he just couldn’t go on. He fell by the side of the road and lay there breathless.
The others stopped to help, but he urged them on, asking them to just leave him there. He had given up all will to live, all desire for life or the future.
The enemy was fast approaching, so the others were anxious to move on. The woman with baby then looked down at the old man and said, “It’s your turn. Everyone else has helped carry the baby. Now it’s your turn. You must fulfill your responsibility.”
