In “Within My Flesh Shall I See God,” section “The Realization of Attainment – Only through the Method of Kabbalah,” Baal HaSulam writes that the denial of Providence is like asking a person: “Who wrote this incredibly wise book?” and him answering that there is no such sage in the world, that everything only happened because his small son spilled ink on blank sheets of paper, and the ink spread to form letters which combined into the words of this incredible science.
By denying the presence of the Upper Governance, people act according to the principle of “whatever I do not feel does not exist.” That’s so even if they see that there is a reason for everything, which is the essence of a materialistic approach.
All of our scientific experiments are based on studying the preliminary causes; otherwise our natural sciences would have no value. But at the same time there are those who deny the existence of the source of the entire creation. Even though man understands that his knowledge is limited and there are many things that he does not grasp or understand, he tries to prove that the universe is exactly what he perceives.
But in order to study the universe, it is necessary to rise above nature because I can study a certain state only when I am above it. In order to study animals I need to be a human for animals cannot study themselves. I can study the stages below me, but I cannot study myself.
Psychology, a science of human behavior, is an example of this. In psychology we base our knowledge on real facts that we have experienced, but we are unable to rise above ourselves to begin to understand the actual methodology of human relationships, the system of connections, or human mentality even though it seems to us like we are capable of doing this objectively.
This is why Baal HaSulam writes that he respects materialistic psychology; its data is based on the study of matter and its form. But until man is able to examine the matter of the spiritual world and the form clothed into this matter, he is unable to say anything about himself, just like a cat is unable to study human behavior or explain its actions.
Thus, Baal HaSulam says that attainment is only possible through the method of Kabbalah because it lifts a person to the next level of consciousness.
