Question: How can we scientifically explain, without mysticism or religious miracles, that reading the books written by Kabbalists helps correct our intention and change one’s inner state?
Answer: What does mysticism or religion have to do with it? Neither are part of Kabbalah.
Reading Kabbalistic books helps orient you internally toward a goal because they speak of how your soul should be aimed toward it. The same way we tune a musical instrument, we tune ourselves by reading Kabbalistic books.
This tuning fork comes through the books. Try reading them and you will feel it. In no way should you deafen it with any religious precepts, obligations, or various mystical bemusements.
