Unlike in our world where faith is called some assumption taken as a fact, in the wisdom of Kabbalah, faith means the sensation of the Creator. Faith is Bina, the property of bestowal. When we acquire it, we reveal the common force which fills the world. Then we feel it, exist in connection with it, and attain it. This is called reason.
In this case, why are we talking about faith above reason? When I exist in the egoistic nature, I have some knowledge or opinion.
In order to rise to the spiritual level, I need an external power which will transform me, and as a result will lift me to a new level of perception above egoism to the property of bestowal. This perception is called faith, the power of Bina. Meanwhile, our corporeal knowledge is received inside us, in the property to receive, in Malchut.
If I have achieved bestowal, faith, the Light of Hassadim (Mercy), then I become filled with the Light of Hochma (Wisdom) or reason. Once I become filled with reason (knowledge), I exist in the next state, in Malchut.
Once again, I have to rise to a higher degree. How do I do that? I do it with the help of faith, the power of Bina, the Light of Hassadim, bestowal. When I have the Light of Hassadim, I fill it with the Light of Hochma again. Then again I have reason (knowledge).
This way I advance by using faith above reason. This is precisely the lever that allows me to rise more and more each time.
