In mysticism, existence is allocated to Almighty God, and it is He who manifests in the universe and without Him whatever appears existing, in the strict look of mysticism, is the manifestation of the reality of His existence which is nothing but His validity and is merely related with Him. Since it is God who has filled the universe, His perfection and beauty can be seen anywhere which is illuminated by His light. But the imperfection and wickedness do not have any connection with Him, but they are of the essence and possible determinations of themselves; and if they are removed, nothing remains except self-existed God. So, we say that in the level of being, God is separate from the others, but in the level of action, He watches them. I have tried, in this article, by description and attribution, to explain the researcher mystics' point of view about existence, appearance and His impression in the universe and show the matter that, by presenting it, the existing world assumes another aspect and finds special beauty. And even with this viewpoint, most of the difficulties arisen in the interpretation of existence, and human being could not easily get rid of the sarcasm of those who deny God's stratagem in the existing world, is removed and the calamities and hardship that believers have suffered throughout the history becomes tolerable.
