Both sides of chastity are surrounded by two negative traits: sharah (insatiability, greed) and humūd (excessive lack of desire, inertia). Sharah is an excessive desire for pleasures (lezzetler) that the rational faculty deems blameworthy and prohibits, while humūd is an excessive lack of desire toward things that the intellect inclines toward and ought to attain. Both are condemned. The middle way, which is chastity, is praised. (Mizān, 67)
The order of these (tawājud, wajd, and wujūd) ḥāl (spiritual states) is as follows: first comes quṣūd (intention), then wurūd (arrival), then shuhūd (witnessing), then wujūd (finding), and finally humūd (extinguishing). Humūd occurs in proportion to the amount of wujūd. The possessor of wujūd has the states of ṣaḥw (sobriety) and maḥw (effacement). (Qushayri, 37)
