In Enneads I 6, 9, Plotinus writes,
Go back inside yourself and look: if you do not yet see yourself as beautiful [i.e., as participating in the Idea of Beauty], then do as the sculptor does with a statue he wants to make beautiful; he chisels away one part, and levels off another, makes one spot smooth and another clear, until he shows forth a beautiful face on the statue. Like him, remove what is superfluous, straighten what is crooked, clean up what is dark and make it bright, and never stop sculpting your own statue, until the godlike splendor of virtue shines forth to you…. If you have become this, and seen it, and become pure and alone with yourself, with nothing now preventing you from becoming one in this way, and have nothing extraneous mixed with your self… if you see that this is what you have become, then you have become a vision.
