Kemāl-i khāṣṣ bi’l-insān (the perfection specific to the human being) refers to the perfection (kemāl) that is unique to the human, and is the apprehension of the reality of intelligible things, as distinct from the faculties of imagination and sensation found also in animals.
Know that the nafs (the lower self) is by its very nature thirsty for perfection and, by its original constitution, is capable of attaining it. However, to the extent that the nafs becomes preoccupied with bodily desires (shahawāt) and things that befall it, and as much as these occupy the body, it is distanced from perfection. The more a person subdues and overcomes his desires, and liberates his intellect from the captivity and bondage of desire, and if he applies his thought and contemplation to the malakūt (spiritual dominion) of the heavens and the earth, to the marvels created therein, and even to reflecting upon himself, he attains the perfection that is perceptible (through the senses). (Mizān, 15)
