Three Things Mastered
There was a relative of the king, named Im Sung-jong, who was a gifted
man in thought and purpose. He was the first performer of his time on
the harp. King Se-jong said of him, "Im's harp knows but one master,
and follows no other man."
His home was outside the South Gate, and every morning he was seen
kneeling on the sill of his front door beating his hands upwards and
downwards on his knees, and this practice he carried on for three
years. People could not imagine what he meant by it, but thought him
mad. Thus he learned the motions required for the harp.
Also he blew with his mouth and practised with his fingers day and
night without stopping, so that when people called on him he would
see them but would not perceive them. He kept this up for three years
and so learned the motions for the flute.
He was a lightly built man in body, and poor at riding and at
archery. He often sighed over this defect, and said, "Though I am
weak and stupid and not able to shoot a long distance, I shall yet
know how to hit the target and make the bull's-eye. This also must be
acquired by practice." So every morning he took his bow and arrows
and went off into the hills. There he shot all day long, keeping it
up for three years, till he became a renowned archer. Thus you may
perceive the kind of man he was.
