God’s permission and tour and gaze upon the manifest world. It also may be said that one type of animal bodies, from the birds of Paradise called ‘The Green Birds’1 in a Hadith, to flies, are the aircraft for a sort of spirit being. They enter them at God’s command, travel around the physical universe, observing the miracles of creation through the windows of the senses of the animals’ bodies.
The Creator, Who continuously creates subtle life and luminous percipient beings from dense earth and turbid water, surely also creates conscious beings suitable for spirit and life, from those seas of light and even from the oceans of darkness. And He creates them in great abundance. The existence of angels and spirit beings has been proved with the certainty of two plus two equals four in my treatise entitled Nokta (Point), and in the Twenty-Ninth Word. If you wish, you may refer to them.
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 revealed 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 can almost be felt 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 do the spirits of the prophets and saints rise there with God’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 what resembles a body and are light and subtle like spirits may rise there.
THIRD STEP: The silence and tranquillity of the heavens, and their order and regularity, and vastness and luminosity, show that their inhabitants are not like those of the earth; they are obedient, they do whatever they are commanded. Because the country is vast there is nothing to cause overcrowding and disputes. Their natures are pure, they are innocent, their stations are fixed.
On the earth, opposites come together, evils are mixed with good, and disputes start between them. For this reason, conflict and suffering are born. And from them examination and competition are set. And from them progress and retrogression occur. The wisdom in these facts is as follows:
