Answer: Kabbalah becomes a science when a Kabbalist is engaged in it.
A Kabbalist is one who has achieved the state of “receiving for the sake of bestowal.” A person who possesses such properties understands the Creator’s actions within himself and in the universe. He becomes a researcher of the entire space revealed before him.
Therefore he is called a Kabbalist. Those who study Kabbalah are the students of Kabbalists for now since they are on the path to the attainment of the spiritual world.
