 When an individual has a very powerful imaginative faculty, to such a degree that it is no longer restricted to the supply of images to the other faculties, it is thus free to experience sensibles of extreme beauty and perfection by means of imitation. The highest rank of perfection that the imaginative faculty can achieve is precisely when an individual attains prophecy or awareness of present or future events, as well as the capacity to see glorious or divine beings. This can be achieved by means of present and future particulars and the transcendent intelligibles of divine beings, both granted by the active intellect. However, al-Fārābī also expounds a series of inferior ranks below this most perfect attainment of vision, each progressively more imperfect than the precedent in terms of whether the vision takes place during waking or sleeping states, and whether the individual has access to particulars or intelligibles. According to al-Fārābī, the most common kind of vision is that of individuals who receive particulars while in the sleeping state.
