"After a long and arduous journey a young Japanese man arrived deep
in a forest where the teacher of his choice was living in a small house he
had made. When the student arrived, the teacher was sweeping up
fallen leaves. Greeting his master, the young man received no greeting
in return. And to all his questions, there were no replies. Realizing there
was nothing he could do to get the teacher's attention, the student went
to another part of the same forest and built himself a house. Years later,
when he was sweeping up fallen leaves, he was enlightened. He then
dropped everything, ran through the forest to his teacher, and said,
'Thank you.'"
