Vision - Words used in a Course in Miracles

Correction is for all who cannot see. To open the eyes of the blind is the Holy Spirit's mission, ... . He would awaken them from the sleep of forgetting to the remembering of God. Christ's eyes are open, and He will look upon whatever you see with love if you accept His vision as yours.      T-12.VI.4:1-4.

 Be willing, for an instant, to leave your altars free of what you placed upon them, and what is really there you cannot fail to see. The holy instant is not an instant of creation, but of recognition. For recognition comes of vision and suspended judgment. Then only it is possible to look within and see what must be there, plainly in sight, and wholly independent of inference and judgment. Undoing is not your task, but it is up to you to welcome it or not. Faith and desire go hand in hand, for everyone believes in what he wants.      T-21.II.8. 

Vision depends on light. You cannot see in darkness. … Dreams disappear when light has come and you can see. Do not seek vision through your eyes, for you made your way of seeing that you might see in darkness, and in this you are deceived. Beyond this darkness, and yet still within you, is the vision of Christ, Who looks on all in light. Your "vision" comes from fear, as His from love. And He sees for you, as your witness to the real world.    T-13.V.8:1,2,9/9:1-4.

What has no meaning cannot be perceived. And meaning always looks within to find itself, and then looks out. All meaning that you give the world outside must thus reflect the sight you saw within; or better, if you saw at all or merely judged against. Vision is the means by which the Holy Spirit translates your nightmares into happy dreams; your wild hallucinations that show you all the fearful outcomes of imagined sin into the calm and reassuring sights with which He would replace them. These gentle sights and sounds are looked on happily, and heard with joy. They are His substitutes for all the terrifying sights and screaming sounds the ego's purpose brought to your horrified awareness. They step away from sin, reminding you that it is not reality which frightens you, and that the errors which you made can be corrected.    T-20.VIII.10. 

Spiritual vision literally cannot see error, and merely looks for Atonement. All solutions the physical eye seeks dissolve. Spiritual vision looks within and recognizes immediately that the altar has been defiled and needs to be repaired and protected. Perfectly aware of the right defense it passes over all others, looking past error to truth.   T-2.III.IV:1-4.
