The fourth stage is Marefat. This is the knowledge which enables a person who has arrived at it to call God "Truth." He applies no other name to God but only truth; in the end of his journey he has found the divine light which is truth, the light illuminating his whole being, the whole universe; and even if a thousand universes were there, they would be illuminated by it.

In the Bible it is said that first there was the Word, and there was Light. That means, that the first or highest knowledge is the truth. Light gives knowledge, words give knowledge; in fact, they are knowledge. The Qur'an says that Allah is the light of the heaven and the earth. That means the illumination to which one attains.

The story of Aladdin, who went in search of the lamp, teaches the same lesson. In the end man arrives at the stage where in the shrine of God he finds the light, the light of truth which illuminates all his life, the light that suffices the whole being. When this light comes, all the fear of God, the confusion, the puzzle are gone, because all such things are due to lack of light. Whatever difficulty might be before us would not dismay us if there were a light for us to see through it.

That which breaks the heart or brings despair is a difficulty or a trouble through which we cannot see; this means that our trouble in life is always lack of light and nothing else; that every difficulty can be solved, and if we understand the nature of our difficulty, we can see our way through. It is the lack of light which prevents our seeing into our trouble, as well as the way out of it, and it is the light which gives us the power to see into our difficulty as well as showing the way out of it.

Therefore what we need in our life is the lamp of Aladdin. That is what is gained at the fourth stage of development, which is called Marefat.
