A mystic does not look at reasons as everybody else does, because he sees that the first reason that comes to his mind is only a cover over another reason which is hidden behind it. He has patience, therefore, to wait until he has lifted the veil from the first reason, until he sees the reason behind it. Then again he sees that this reason which was hidden behind the first reason is more powerful, but that there is a still greater reason behind it. And so he goes from one reason to another, and sees in reason nothing but a veil to cover reality. And as he goes further, penetrating the several veils of reason, he reaches the essence of reason. By touching the essence he sees the reason in everything, good and bad.
