Kabbalah’s Definition of Faith Compared to a Common Understanding of Faith
A question I received: How can you empirically prove that this faith (Emuna) is the right one? For example, you know that the sun exists because you see it up in the sky.
My Answer: You’re confusing faith as it’s understood by people in our world with faith as defined by Kabbalists. Faith (Emuna) is the quality of bestowal, which enables you to see a different world. It’s a different sense of perception, where you perceive outside of yourself, above your personal calculations. This is the reason why people who have faith change completely.
On the other hand, you are defining faith as believing in something somebody said. In other words, you believe that what you heard is a fact. Since it is a science, Kabbalah denies such an approach. In Kabbalah, you accept something in order to test it yourself. To acquire faith means to acquire a screen, the ability to feel, define, and measure sensations that are tuned to bestowal and love.
Love is characterized by giving. I love – means I give; I enjoy from pleasing the other. How could it be that I please the other? What do I please him with? With my attitude toward him. How can he receive pleasure from me? Only if he loves me. In this case, if I relate to him with love, he receives pleasure from it. However, if I don’t love him, I will perceive his good attitude toward me as hatred, and this will push me away from him even more.
