We need information about the world and ourselves, and further information to help us realize what know. All human knowledge accumulated until now has not led us to a life of happiness, but to a deadlock and collapse of the system, and everything we produce eventually turns against us. The wisdom of Kabbalah gives a person information about the system that manages him and the possibility of integrating in it, but this upper knowledge opens up to a person provided he learns to control his evil inclination, his heart.
