Answer: Kabbalah is a wisdom that explains how the altruistic or spiritual forces descend into this world. These properties of bestowal and love are completely opposite to the earthly ones. They gradually come closer to humanity, and that is why we suffer.
One can say that we suffer because the Creator is approaching us. We feel how opposite we are from Him and that is why we feel bad. The properties of bestowal, love, and unification become closer to us while we, in accordance with our nature, do not want it. This is the problem we encounter our entire life.
Because we do not recognize it, whatever happens to us on Earth is not felt like an awakening to spiritual ascent, but like events that repel and humiliate us.
If we realized the origin of our suffering, the fact that we suffer because spiritual forces become closer to us, and accordingly, if we become more and more like these spiritual forces, the qualities of bestowal, love, and unification, we would then perceive them correctly, we would be in contact with them and feel how they help us ascend to a completely different height of qualities, the spiritual degrees.
