When people say that they distinguish between right and wrong by their results, even then they cannot be sure if in the punishment there was not a reward, or in the reward a punishment. What does this show us? It shows us that life is a puzzle of duality. The pairs of opposites keep us in an illusion and make us think, 'This is this, and that is that'. At the same time by throwing a greater light upon things we shall find in the end that they are quite different from what we had thought.
Seeing the nature and character of life the Sufi says that it is not very important to distinguish between two opposites. What is most important is to recognize that One which is hiding behind it all. Naturally after realizing life the Sufi climbs the ladder which leads him to unity, to the idea of unity which comes through the synthesis of life, by seeing One in all things, in all beings.
