While Jesus is sitting with His disciples on the Mount of Olives, the Document goes on to say, there descends upon Him a “Great Power of Light,” which is in fact the “vesture” or Heavenly Nature which He had left in the Limit or Lower Boundary of the upper worlds on His descent to earth in “the shape of Gabriel.” This vesture enables Him to rise to the Boundary and there assume two other vestures which are necessary for the continuation of the journey to the two transcendental “Spaces” which are higher than this. In this first vesture, also, He finds five mysterious words written which are here interpreted as an address from the higher powers hailing Him as the First Mystery, and the catalogue of names which follows enables us to form a fairly correct idea of the arrangement of this Chorema as well as of the higher ones which are known as the “Spaces” of the First Mystery and of the “Ineffable” or Supreme Unmanifested God respectively.[19] On assuming this vesture, Jesus flies into the Height, but returns the next day clad in three vestures of dazzling light, and tells His disciples how He provided for the births of Himself and them by casting into their respective mothers Powers from the higher parts of the Kerasmos instead of the material souls which they would otherwise have received from the Rulers of the stars. In like manner also, He tells how He caused the soul of Elijah to become incarnate in the body of John the Baptist. He then goes on to describe His journey upward through the First Sphere directly above the firmament, the Second Sphere called Destiny, and the Twelve Æons,[20] which appear to be the signs of the Zodiac. The Kings or Tyrants of these last rebel against Him, and He punishes them by taking away part of their power and altering their course, so that mankind will no longer be able to foretell the future by means of the astrology and magic taught them by the sinning angels. Leaving their Place, He ascends to the thirteenth Æon, and finds below it Pistis Sophia, the heroine of the book. She is, it appears, one of the twenty-four Unseen or Invisible Ones put forth in pairs by the head of the Left Hand or most material part of the Kerasmos, and had left her spouse and her work to pursue a light which she saw below her and which she thought would enable her to mount to the Treasure-house. This light, however, was a snare sent into Chaos by one of the material Powers immediately above her; and on her advancing to seize it, she was set upon by several material Powers that her persecutor had put forth and deprived of her own light, so that she could not return to her own Place in the thirteenth Æon.
