When Allah - glory be to Him! - willed that the source of His most Beautiful Names - which are beyond enumeration - be seen (or you can equally say that He willed His source to be seen), He willed that they be seen in a microcosmic being which contained the entire matter,1 endowed with existence, and through which His secret was manifested to Him. For how a thing sees itself through itself is not the same as how it sees itself in something else which acts as a mirror for it. So He manifests Himself to Himself in a form which is provided by the place in which He is seen. He would not appear thus without the existence of this place and His manifestation (tajalli) to Himself in it.
Allah brought the entire universe into existence through the existence of a form fashioned without a spirit (rأ»h), like an unpolished mirror. Part of the divine decree is that He does not fashion a locus without it receiving a divine spirit, which is described as being "blown"2 into it. This is nothing other than the result of the predisposition of that fashioned form to receive the overflowing perpetual tajalli which has never ceased and which will never cease.
Then we must speak of the container (qأ¢bil). The container comes from nothing other than His most sacredly pure Overflowing. So the whole affair has its beginning from Him, and its end is to Him, and "the whole affair will be returned to Him" (11:123) as it began from Him. Thus the command decreed the polishing of the mirror of the universe. Adam was the very polishing of that mirror and the spirit of that form.
