Answer: The wisdom of Kabbalah was revealed and developed in two directions, one is the intellect and the second is in feeling.
A person is a sensory creature because the desire for fulfillment, for enjoyment is the foundation his being. But when this desire begins to feel that it wants more, wants less, receives less, receives more, and so forth, then the intellect develops within it with the function to think about how to reach the best fulfillment. It follows that there are feelings and there is the intellect, but the feelings are primary and the intellect is secondary.
Studying the wisdom of Kabbalah happens the same way, in two parallel ways: emotional and intellectual. The books that correspond to the emotional way are Shamati and Attaining the Worlds Beyond. And for the intellectual way there is Kabbalah for Beginners.
I believe that it is necessary to try both of them. Read the book that is closest to you.
