Nothing is created without a purpose; the physical world is governed by precise laws of motion, transformation, and circulation. However, the main question—“Why does it all exist (not only us, but the entire universe)?”—remains unanswered. Is there anyone in this world who has not been touched by this question at least once?
According to Kabbalah, there exists a spiritual world that is imperceptible to our sense organs. At its center is one tiny part—our universe and our planet–the heart of this universe. This sphere of information, thoughts, and emotions affects us through the laws of the material nature and its incidents. It also places us under certain conditions upon which we must act. To receive absolute fulfillment, we must acknowledge the need for spiritual elevation above matter. There are two paths in our world to reach that goal: the path of the spiritual ascent (Kabbalah), and the path of suffering.
