The similitude of this world is like that of a vessel filled with honey. The flies see this vessel and fly toward it. Some of them sit on the edge of the vessel and take from the honey until they satisfy their needs, and then they fly away. Some of them are led by their greed to plunge themselves into the abyss of the honey. Their submersion into the honey prevents them from enjoying it, except for a brief enjoyment, until they perish in the middle of it.
