Second Step:
The earth and the heavens are connected to one another like two countries under a single government. There are important relations and transactions between them. Things necessary for the earth like light, heat, blessings, and mercy in the form of rain come from the sky, that is, they are sent. According to the consensus of the heavenly religions, which are founded on revelation, and the agreement of all those who uncover the mysteries of the universe, relying on what they have witnessed, the angels and spirit beings descend to the earth from the skies.
From this it may be understood through a surmise so certain it is almost perceptible that for the inhabitants of the earth there is a way to ascend to the heavens. Indeed, everyone’s mind, imagination, and gaze perpetually rise to the skies. So too, having discarded all heaviness, the spirits of the prophets and saints rise there with Allah the Most High’s permission, and having stripped off their bodies, the spirits of the dead. Since those who become light and subtle rise to the heavens, for sure, one sort of the inhabitants of the earth and the air who are clothed in wraith‑like bodies and are light and subtle like spirits may rise there.
