Therefore, when everyone on earth discovers spiritual unity with God, people will realize that all God's actions are good. For Kabbalists their ultimate aspiration is to reach a oneness with God. Every person should strive to attain this spiritual oneness by ascending from one world to another. At the final level, a person, usually through extensive meditation and a departure from the body, arrives in a state of total knowledge of the universe. All creation evolves around this goal.
Light plays an important role in the spiritual life of a Kabbalist.
They refer to the Impression of Light as the source of humanity, the lower beings, who exist in the fallible state. God hovers above the fallible lower beings as the Infinite Encircling Light. He interacts with the fallible beings through a Line of Light in an attempt to help them reach perfection. The Line of Light is God's way of instilling perfection and abolishing all imperfection. To the Qabalists, man exists parallel to the universe as a whole.
