It is not possible to PERCEIVE **within** reality, because there is no perception WITHIN reality. Perception is an interpretative process based on judgement. You can evaluate reality and PERCEIVE it, but this isn't the SAME as knowing it or DIRECTLY experiencing it.
"Only your vision can convey to you what YOU can see. It reaches you directly, without a need to be interpreted to you."
Perception ends before you enter the Kingdom, this does not mean that you cannot SEE in some manner WITHIN the Kingdom.
"Only the mind CAN SEE."
In fact, after an extensive search, I found a great deal of evidence in ACIM that mind in fact DOES have a permanent ability to see. And that even God can see. This seeing does not use PERCEPTION, however. It uses cognition, recognition, and knowledge.
It is possible to KNOW reality, and to RE-COGNIZE God and your brothers. This knowing is a DIRECT experience of what IS THERE. You KNOW it, in awareness. This may well not entail BODIES, but you are SPIRIT, and spirit can be known and SEEN. The son of God can also be seen. YOU are a perfect shaft of light, which can be seen. The great rays can also be seen and they stretch to infinity.
Perception is a way of seeing based on JUDGING or EVALUATING what is there. It is interpretative. Beyond perception, WITHOUT judgement or interpretation, you can directly KNOW what is there. This knowing isn't just some fact or piece of information of non-visual experience. You can SEE GOD and His Creation - the universe of love. Knowing is UNDERNEATH perception and provides direct awareness of reality.
I will present below only a small segment of all the quotes I found. These ones speak more directly to seeing in God, seeing God, seeing His Son, God's ability to see, beyond perception, and beyond vision.
"Perception can reach everywhere under His guidance."
"Perception changes, made to take the place of changeless knowledge. Yet is truth unchanged. It cannot be perceived, but only known." (does not mean it cannot be SEEN!)
"To perceive the truth is not the same as knowing it."
"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***"
"God knows His Children with perfect certainty. He Created them by knowing them. ***He recognizes them*** perfectly."
"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.***"
"The soul never leaves ***the sight of God***"
"ONLY what God creates, or what man creates with the same will, ***has any real existence***. ***This, then, is all that the innocent can see.***"
"The wish to see calls down the grace of God upon your eyes, and brings the gift of light that makes sight possible. ***Will you behold your brother? God is glad to have you look on him.***"
"***See His creations as His Son***, for yours were created in honor of Him. The universe of love does not stop because you do not see it, nor have your closed eyes lost the ability to see. ***Look upon the glory of His creation***, and you will learn what God has kept for you."
"***You will see that God Himself*** is where his body is. Before this light the body disappears"
"***God is in everything I see*** because God is in my mind."
"***God is the light in which I see.***"
"***You cannot see apart from God*** because you cannot be apart from God."
"When you ***look upon knowledge***, all judgment is automatically suspended, and this is the process that enables ***recognition to REPLACE perception.***"
"Judgment is the process on which perception but not ***cognition*** rests." ... "It is ***perfectly possible to look on reality without judgment***, and merely ***KNOW it is there*** By knowing this, you are not doubting its reality at all."
"The innocent see safety, and ***the pure see God within His Son***, and look unto the Son to lead them to the Father."
