Notion of emenation in neoplatonic philosophy

Answer: In neoplatonism the divine (necessary existence) is devoid of composition, which is ontological composition which also entails contingency in the essence of the necessary existence so that is to say, the philosphers posit that the multiplicity cannot emenate from the essence of necessary existence because otherwise it would entail plurality of beings, which is impossible since it violates the law of identity, so that whatever emanates is ontologically simplest (not in a literal meaning) as by simple or in arabic (بسيط) they mean that which has gained perfection through its ontological union with the necessary being and is only one, in essence but it is contingent since it is composite of both existence and essence, so human soul came into existence in latter realms which is not intellecting realm (عالم العقل) but it is (عالم الأرواح) imaginable realm (which is metaphysical) and it has more gradation in existence, from the sense that it has more multiplicity so the human soul (being eternal and imperfect in essence) has to gain the perfection [ontological perfection] through having an affinity with the first intellect which is deemed as (عقل الأول) which is direct emenation from the necessary being and without having a mutual affinity with the first intellect it is not possible to have affinity with the necessary being itself, the first intellect only realizes itself and the effect (in cause and effect series) which means it posseses the attribute of knowledge, so the entitle of it is identical to the first intellect.
