Question: Is it possible to say that the worldview of a person who studies the wisdom of Kabbalah correctly is similar to the approach of a scientist who knows that his egoism inserts errors into measurements?
Answer: Someone who studies the wisdom of Kabbalah begins to work with himself correctly, with his egoism and with the quality of the Light, meaning with absolute altruism. He puts the two forces, the force of the Light and the force of the ego, one against the other and begins to gather new forms of existence in life within them where these two opposing forces are integrated together. A person exists between them as the middle line. That is how he builds himself.
Therefore, the wisdom of Kabbalah is a very practical science. This means that to the same degree that a person attains the positive force and the negative force of this world, he builds himself, his world, and what is called the Temple, in a connection between the negative force and the positive force, and creates a place called his soul within which he discovers the Creator.
