When your body's eyes are looking at forms, which includes ALL PHYSICAL OBJECTS, you are blind. Yet the body's eyes CAN ONLY EVER see physical forms.
REASON, sees past ALL FORMS, because it recognizes that all forms are FORMS OF ERROR, and reason recognizes they are an ERROR.
Reason, takes you toward understanding, which is BEYOND PHYSICAL MATTER.
Reason overlookes, forgives, physical matter, and gives you a vision of what matter was trying to OBSCURE, through its forms of error.
Reason does not BELIEVE physical matter. It does not believe what the body's eyes show you.
Since everything the body's eyes see is ALWAYS AN ILLUSION, the idea that NOTHING is something real (there is no world), overlooking what the body's eyes see allows you to SEE SENSE and awaken to the truth.
Unless you see past form - the physical planet - to the truth, you do not understand reality. Because in reality, there is no world.
As Jesus states CLEARLY:
"You can SEE reason. 5 This is not a play on words, for here is the beginning of a vision that has meaning. 6 Vision is sense (stuff that 'makes sense'), quite LITERALLY. 7 If it is not the body's sight, it must be understood." (understanding is only found by looking past the body).
"For reason SEES THROUGH ERRORS (errors are forms, physical matter), telling you WHAT YOU THOUGHT WAS REAL IS NOT. 4 Reason can see the difference between sin and mistakes, because it wants correction. 5 Therefore, it tells you what you thought was uncorrectable can be corrected, and thus it must have been an ERROR." (physical matter is a 'correctable error).
"Reason is not salvation in itself, but it makes way for peace and brings you to a state of mind in which salvation can be given you. 2 SIN IS A BLOCK (to awareness), set like a heavy gate, locked and without a key, across the road to peace. 3 No one who LOOKS ON IT without the help of reason would try to pass it. 4 THE BODY'S EYES BEHOLD IT AS SOLID (yes, your fricking EYES are LOOKING AT SIN) granite, so thick it would be madness to attempt to pass it. 5 Yet reason SEES THROUGH IT (sees through physical matter), because it is an error. 6 The FORM (physical form) it takes cannot conceal its EMPTINESS from reason's eyes."
"If what the FORM CONCEALS is a mistake, the form cannot prevent correction. 3 THE BODY'S EYES SEE ONLY FORM. 4 THEY CANNOT SEE BEYOND what they were made to see. 5 And they were MADE TO LOOK ON ERROR AND NOT SEE PAST IT." ... "THESE EYES, MADE NOT TO SEE, WILL NEVER SEE." .... "Only mistakes have different FORMS (physical forms), and so THEY (physical forms) CAN DECEIVE."
"Reason will tell you that IF FORM IS NOT REALITY IT MUST BE AN ILLUSION (physical forms are illusions), and IS NOT THERE TO SEE (there is no world). 5 And if you see IF YOU SEE IT YOU MUST BE MISTAKEN, for YOU ARE SEEING **WHAT CANNOT BE REAL** AS IF IT WERE. 6 What cannot see beyond what is not there must be distorted perception, and must PERCEIVE ILLUSIONS (physical matter) as truth. 7 Could it, then, recognize the truth?"
"Let not the vision of his holiness, the sight of which would show you your forgiveness, be kept from you by what the body's eyes can see" (his holiness is beyond physical matter).
