What is the difference between the method of Kabbalah and Musar (moralism)?
Kabbalists tell us that the only force that can correct the human soul is the Light that reforms. The Upper Light, the Creator created the human desire; hence, the light is the only thing that can correct it. This is why the wisdom of Kabbalah is the only cure against the egoistic desire imprinted in each and everyone of us. There is a huge force in the authentic sources of Kabbalah, which can reform a person. One who studies from the original texts is reformed and is awarded the quality of bestowal. And such a person does not need Musar.
