Here are statements demonstrating that you can SEE real stuff. Seeing God, seeing the Son of God, seeing Christ, seeing the Kingdom. Note that perception of reality is NOT the same as being IN reality. But some of these quote infer you can SEE WITHIN REALITY (not using perception).
"God is in everything I see because God is in my mind." <- God is seen "beyond" the physical.
"The idea for today is the springboard for vision. From this idea will the world open up before you, and you will look upon it and see in it what you have never seen before. Nor will what you saw before be even faintly visible to you." <- reality is seen in/beyond it.
"Blessed are the pure in heart for they shall see God" is another way of saying the same thing. Only the innocent CAN see God." <- you can SEE GOD.
"The innocence of God is the true state of the mind of His Son. In this state, man's mind DOES see God, and because he sees Him as he Is, he knows that the Atonement, NOT sacrifice, is the ONLY appropriate gift to His OWN altar, where nothing except perfection truly belongs." <- this suggests there is SEEING, but we know there is no PERCEPTION in heaven. "only the mind sees" clues us in that mind can actually SEE within heaven, without the need for "perception"?
"Today we will attempt to see God's Son. We will not let ourselves be blind to him ; we will not look upon our grievances." <- It must be possible to SEE God's Son, who is real, and is in reality.
"This is the way in which you MUST perceive God's Creations, bringing all of your perceptions into the one parallel line which the Holy Spirit sees." <- Not only is there an ability of mind to SEE God, there is also an ability to use PERCEPTION to see God from within the dream - to see Him AND His creations. You can see the soul?
"For who could see the Son of God as innocent and wish him dead? Christ stands before you, each time you look upon your brother." <- Apparently possible to "look at" with vision, your REAL brother, who is in heaven.
"Nothing that you remember, that made your heart seem to sing with joy, has ever brought you even a little part of the happiness this sight will bring you. FOR YOU WILL SEE THE SON OF GOD. You will behold the beauty that the Holy Spirit loves to look upon, and that He thanks the Father for. He was created to see this FOR you, until YOU learn to see it for yourself. And all His teaching leads to seeing it, and giving thanks with Him." <- clearly possible to SEE God's Son who is IN REALITY, either through direct mind seeing or through perception.
"This loveliness is NOT a fantasy. It is the real world, bright, and clean, and new, with everything sparkling under the open sun. Nothing is hidden here, for everything has BEEN forgiven, and there ARE no fantasies to hide the truth." <- "real world" here refers to HEAVEN.
"For forgiveness literally TRANSFORMS vision, and lets you see the real world, reaching quietly and gently across chaos, and removing ALL illusions that had twisted your perception, and fixed it on the past." <- "real world" again refers to HEAVEN.
"For every grievance is a block to sight, and as it lifts, you see the Son of God where he has always been. He stands in light, but you were in the dark." <- to see the son of God as where he as always been, you must see him in HEAVEN.
"You who believe that you can choose to see the Son of God as you would have him be, forget not that no concept of yourself will stand against the truth of what you are." <- implies you can see him as you would NOT have him be.
"To believe that you can perceive the real world is to believe that you can know yourself. You CAN know God, because it is His Will to BE known." <- again "real world" means HEAVEN. Perception is happening IN the dream, but perceiving beyond the dream.
"The Soul always remains changeless, because it never leaves the sight of God." <- this is not perception but, interestingly, suggests God can "see".
"Sit quietly and look upon the world you see, and tell yourself, "The real world is not like this. It has no buildings, and there are no streets where people walk alone and separately. There are no stores where people buy an endless list of things they do not need. It is not lit with artificial light, and night comes not upon it. There is no day that brightens and grows dim. There is no loss. Nothing is there but shines, and shines forever." This world you see MUST BE DENIED, for sight of it is costing you a different kind of vision. YOU CANNOT SEE BOTH WORLDS. For each of them involves a different kind of seeing, and depends on what you cherish. The sight of one is possible because you have DENIED THE OTHER. ... Both are not true, yet either one will seem as real to you, as the amount to which you hold it dear." <- I believe this is talking about Heaven as the real world and having sight of it, as another world, whereby sight of THIS world blocks your vision of The Kingdom. Therefore you can PERCEIVE Heaven. Also "Nothing is there but shines, and shines forever" indicates the "real world" *ABSOLUTELY MUST* be a reference to HEAVEN, not to a temporary dream-state perception, because only Heaven last FOREVER and the real world SHINES FOREVER.
"No-one in this distracted world but has not seen some glimpses of the other world about him. But while he still lays value on his own, he will DENY the vision of the other world, maintaining that he loves WHAT HE LOVES NOT, and following not the road that love points out." <- sight of another world requires ability to perceive heaven. Having glimpses of another world is having glimpses of REALITY.
"Your holy brother, sight of whom is your release, is no illusion." <- Your brother is REAL in heaven, not an ego illusion, and you can have SIGHT OF him, thus see his soul.
"You would not do this, except for your UNWILLINGNESS to perceive reality, WHICH YOU WITHHOLD FROM YOURSELF." <- Thus you can perceive reality.
