His son was very surprised because he knew that this teacher was not well-educated, he was illiterate. He was not of high birth, he had no special reputation, he was not famous in any way. He was just living in a village in humble guise. For all that his father sent him there. So he travelled on foot, not very willingly, till he came to the village where this peasant dwelt. It so happened that he was travelling on horseback from his own farm to another, and he saw the young man coming towards him. When he came up to the young man, he looked upon him as he bowed before him. But the teacher said, "Not enough." So he bowed to his knees. The peasant teacher again said, "Not enough." So he bowed down at his feet, and still the teacher said, "Not enough." Then he bowed down at the horse's knees. But still the teacher said, "Not enough." So the young man bowed again at the horse's feet, but this time touched the horse's hoof. Thereupon the peasant teacher said, "You can go back now, you have had your training." That was all! No exercises, no word to learn, nothing to study, no training course. He had learnt the lesson he had to learn; it was for that his father sent him, it was for that lesson he came. And now he was admitted to the circle of the mystics.
