fass-i ḥikmat-i rūḥiyya

Fass-i ḥikmat-i rūḥiyya (chapter of the wisdom of the spirit), that is, sciences specific to understanding solely through the rūḥ (spirit), according to Yaʿqūbī, are sciences entrusted to the rūḥ (spirit) of this Prophet. It is preferable to read it as rūḥiyya rather than rawḥiyya. In this ḥāl (spiritual state), what is intended here is the form rūḥiyya. For all the sciences mentioned in this chapter pertain to the perception and characteristics of the rūḥ. (Ṣūfyāvī, 139)
