Dhammapada Verses 143 and 144
The Story of Thera Pilotikatissa
Once, Thera Ananda saw a shabbily dressed youth going round begging for food; he felt pity for the youth and made him a samanera. The young samanera left his old clothes and his begging plate on the fork of a tree. When he became a bhikkhu he was known as Pilotikatissa. As a bhikkhu, he did not have to worry about food and clothing as he was in affluent circumstances. Yet, sometimes he did not feel happy in his life as a bhikkhu and thought of going back to the life of a lay man. Whenever he had this feeling, he would go back to that tree where he had left his old clothes and his plate. There, at the foot of the tree, he would put this question to himself, "Oh shameless one! Do you want to leave the place where you are fed well and dressed well? Do you still want to put on these shabby clothes and go begging again with this old plate in your hand?"
