On the other hand, the faithful ones of God, (the children of God) possess freedom, true freedom, which consists in knowledge of the Truth, that is, of Christ.Only with this knowledge do the nuptial doors open, from which the soul beholds the wondrous light of the incorruptible essence of the cosmos. The thoughts of these children of God are good, peaceful, and gladdening. "Become peaceful within yourself", says a certain Saint, "and heaven and earth will become peaceful. Enter into the chamber that is within you, and from there you will behold the palace of heaven."
The things that exist in the incorruptible heaven that has been revealed by Christ, and at which the soul looks from the mystical chamber that is inside us, are the true things. They are blessed, peaceful isles in the ocean that extends beyond every material constellation and are outside the slavery of space and time.
