Answer: This is a good question because the feeling of the concealed comes to a man as he looks for this concealed force. This concealed force is called bestowal. If a person looks for it, he feels how distant it is and how it evades him and remains concealed. Then he begins to work in order to attain it.
If this force becomes the most important, greatest, and most respected thing for him it means that he has already acquired the greatness of the Creator. Then a person begins to feel that he doesn’t even need that the Creator be revealed to him and doesn’t even expect the concealed to become revealed. He only wants to bestow back in order to delight the concealed.
Even if he doesn’t know that it bestows, and doesn’t even know that he bestows, and the concealed doesn’t know that he bestows, it is enough for him. Thus a person also becomes concealed from himself, like the force that he wants to reveal.
Then he reaches an equivalence of form with this force and becomes internally familiar with the force called the concealed. It is not revealed, but a person knows it since he has reached the same state. This means “from Your actions we will know You.”
