Memory, of course, must be understood not merely of what might be called the sense of remembrance, but so as to include a condition induced by the past experience or vision. There is such a thing as possessing more powerfully without consciousness than in full knowledge; with full awareness the possession is of something quite distinct from the self; unconscious possession runs very close to identity
— Plotinus
Plotinus is making a distinction that cuts against the way we usually prize awareness. Conscious knowledge, he says, holds the object at arm's length — you know you have it, which means you and it are still two things. Unconscious possession presses toward identity: the thing and the possessor converge until there is no gap to report across.
This is not mystical consolation. It is a description of how spirit works, and it is precise enough to be uncomfortable. The pneumatic current has always promised that if you ascend far enough — if you become aware enough, integrated enough, enlightened enough — you will finally possess what you are seeking. But Plotinus quietly dismantles that promise from the inside: the most complete possession is the one consciousness cannot register, because consciousness requires the distance that makes possession incomplete. The higher you climb toward full awareness of unity, the more you confirm the duality you hoped to dissolve.
What this leaves the soul with is not a method. The ordinary mind looks for technique — a practice, a discipline, a form of attention that will close the gap. But the gap is constitutive of that kind of looking. What runs very close to identity is not achieved; it is already underway, beneath the threshold of every strategy aimed at it.
