What would happen if one of the pots didn’t have a crack?

Answer:

The water-bearer could not pick beautiful flowers.
Discussion:
The water-bearer felt sorry for the old cracked pot, and in his compassion he said, “As we return to the master’s house, I want you to notice the beautiful flowers along the path.”
Indeed, as they went up the hill, the old cracked pot took notice of the sun warming the beautiful wild flowers on the side of the path, and this cheered it some. However, at the end of the trail, it still felt bad because it had leaked out half its load, and so again it apologised to the bearer for its failure.
