Kabbalah is the soul of Torah. Kabbalah is the study of the soul: The human soul, and the soul of Torah, and the soul of everything in the material world.
“There are many layers to reality. The material world experience as we know it is just the surface level, within which exist many dimensions of spiritual energy waiting to be released. By appreciating these inner layers, we can learn to make order out of disorder, to gain insight into the unknown forces that determine all movement and behavior.” — From Toward a Meaningful Life by Rabbi Simon Jacobson
