Jewish Mysticism
R. Simeon bar Yohai was the righteous one, foundation of the world, and by means of his studying this [esoteric[ wisdom with which he was occupied… he united [the masculine] Ze‘eir ’Anpin with his female [counterpart, i.e., Shekhinah]… This is the secret of all those who write mystical books- they repair the world of action by the secret writing of these esoteric truths. The esoteric truth unites Ze‘eir ’Anpin with his female counterpart in the most inward way.
