The angels are some of the faculties of that form which is the form of the universe, which the Sufis designate in their technical vocabulary as the Great Man (al-Insân al-Kabîr), for the angels are to it as the spiritual (rûhânî) and sensory faculties are to the human organism. Each of these faculties is veiled by itself, and it sees nothing which is superior to its own essence, for there is something in it which considers itself to be worthy of high rank and an elevated degree with Allah. It is like this because it has an aspect of the divine synthesis (jam'îya). In it is something which derives from the divine side and something which derives from the side of the reality of the realities. This organism carries these attributes as determined by the universal nature which encompasses the containers of the universe from the most exalted to the basest. However, the intellect cannot perceive this fact by means of logical investigation – for this sort of perception only exists through divine unveiling by which one recognises the basis of the forms of the universe which eceive the spirits.
