I know many methods and teachings to achieve spirituality. Why choose Kabbalah?
The difference between all the teachings and the Kabbalah, as I understand it from the perspective of the Kabbalah, is that they are built on the nullification of desires, or at least on their complete suppression. Kabbalah, however, states that the Creator can be sensed precisely by expressing the desire for Him (certainly not by nullifying it), but inverting the aim of its use. Which way should a person choose to advance? That is an individual choice.
