Within this discussion, the Zohar stresses the importance of properly preparing oneself - mind, body and soul - before entering the gates of Torah study. The reason given by the Zohar concerns the supernal forces and the souls of the righteous, who traverse many worlds to join us whenever we learn. True spiritual study does not pertain to the acquisition of external knowledge. Learning and studying the secrets of the Torah is the sum and substance of Light Itself. Specifically, study and Light are one and the same. Therefore, when we study, we are, in reality, bringing the spiritual forces of Light into full manifestation. This understanding helps us prepare our entire being, so that we may become worthy vessels for the Light of the Creator to fill.
