Question: Can we bring harm to the world by studying the wisdom of Kabbalah like the harm caused by the egoistic use of external science?
Answer: Through discovery of Kabbalah it’s impossible to do any harm because there is a natural filter that transfers only good influence from us to the upper world, to the system of forces that manage reality. Bad influence can never go there.
But when the time comes that you must have a good influence on that system and you don’t, then you have a bad influence on it, not directly, but indirectly. You don’t damage the system willingly, and don’t even know it.
But this is speaking only about your lack of correction. You cannot intentionally cause destruction in the higher system. Deliberately you can only correct. You cannot add your efforts to provide a good influence, but a bad influence is impossible.
