MacKenna-Plotinus: intellective life

(18) But how does the soul enter into body from the aloofness of the Intellectual? There is the Intellectual-Principle which remains among the intellectual beings, living the purely intellective life; and this, knowing no impulse or appetite, is for ever stationary in that Realm. But immediately following upon it, there is that which has acquired appetite and, by this accruement, has already taken a great step outward; it has the desire of elaborating order on the model of what it has seen in the Intellectual-Principle: pregnant by those Beings, and in pain to the birth, it is eager to make, to create. In this new zest it strains towards the realm of sense: thus, while this primal soul in union with the Soul of the All transcends the sphere administered, it is inevitably turned outward, and has added the universe to its concern: yet in choosing to administer the partial and exiling itself to enter the place in which it finds its appropriate task, it still is not wholly and exclusively held by body: it is still in possession of the unembodied; and the Intellectual-Principle in it remains immune. As a whole it is partly in body, partly outside: it has plunged from among the primals and entered this sphere of tertiaries: the process has been an activity of the Intellectual-Principle, which thus, while itself remaining in its identity, operates throughout the soul to flood the universe with beauty and penetrant order - immortal mind, eternal in its unfailing energy, acting through immortal soul. Enneads   IV,7,13

This means in sum that the life the soul takes thence is an intellective life, a trace of the life in the [divine] Intellect, in which alone the authentic exists. Enneads V,3,8

It is The Good since, being a power [being effective outwardly], it is the cause of the intelligent and intellective life as of life and intellect: for these grow from it as from the source of essence and of existence, the Source as being One, simplex and first because before it was nothing. All derives from this: it is the origin of the primal movement which it does not possess and of the repose which is but its absence of need; for neither rest nor movement can belong to that which has no place in which either could occur; centre, object, ground, all are alike unknown to it, for it is before all. Yet its Being is not limited; what is there to set bounds to it? Nor, on the other hand, is it infinite in the sense of magnitude; what place can there be to which it must extend, or why should there be movement where there is no lacking? All its infinitude resides in its power: it does not change and will not fail; and in it all that is unfailing finds duration. Enneads V,5,10
