A story is told about two great men, a father and a son.
They were great leaders, both of them, and the father was possibly one of the outstanding people of his time.
He was passing by his son’s home one day and he heard a baby crying.
He looked and found the baby ,and his son, who was sitting near the cradle, immersed in meditation.
The father soothed the baby and then he shook his son and said to him, “My son, I didn’t know you had such a little mind, because even when I am in the deepest meditation, I can still hear a fly moving about.”
