The thing about the body is that it's a limitation. You as a spirit are unlimited, infinite, everywhere. You are omnipresent like God. To seemingly "enter" a body you have to massively confine yourself to one location, separated off from the rest. It's like having your hands tied. Huge amounts of awareness have to be shut out. Not to mention that your intimate expansive unified relationships with the entire Sonship are shut out.
You are squeezed into this tiny little space that you then seem to inhabit. The body forms this fence around a part of the mind and seems to keep it inside, protected and separate from the rest of the mind which is outside. Large distances are placed between bodies to ensure they are kept separate. This is all the ego's design for isolating and imprisoning God's children.
Then the ego goes one step further and says, ok, now that you are in this body, wouldn't it be great if you could connect with other people? How about we bring your body closer to other bodies? How about we have your bodies try to join with other bodies? Maybe you'll feel wonderful things as you merge and feel close to others. And the usual response to this temptation is that is sounds great, it seems like an improvement, we don't have to be so alone and isolated.
The problem here is that we're accepting a massive artificial limitation as though it can never be changed, we're deliberately confining ourselves to being trapped in a little body, acting from littleness. We're handicapping ourselves, and then pretending that to bring bodies together is going to somehow "undo" this. But so long as the handicapping nature of the body is maintained, so long as we are isolated in space and time, anything the ego offers as a special relationship is a ridiculous substitute for true joining.
Two spirits should share, join, merge, connect, be one, and access each other fully and completely and in a truly unlimited way. You are in your brother's minds. You share everything with them. To do that, you need to not be restricted and limited. Trying to first accept massive limitation and to then try to continue to join, is like two people with a ball and chain around their ankles, chained up to separate prison cells, trying to reach out to be closer to each other. They can't leave the prisons or get past the bars.
It's also a simple fact that nothing in spacetime can truly join. Quantum particles are designed to be separated off. If atoms were to truly occupy the same space they would annihilate each other in a nuclear explosion. Forces repel the particles and keep them separated. Even what seems to be a physical collision or sensation of touch is really what it feels like to bump up against these force fields. Atoms don't ever really touch each other at all. So right off the bat the ego has made this scenario where even if it looks as though you are as physically close to something as possible, you still aren't actually making real contact. All sensations of touch are sensations of two forcefields repelling each other.
To try to join with another spirit while having a body is next to impossible. Someone who knows they are spirit would also find it pointless and very limiting to try to make this connection via the body. Why, when you can experience direct mind-to-mind communication ("minds need not bodies to communicate"), would you first filter all communication through your body, then through another body, in attempting to share something? Why not just go mind-to-mind?
When two bodies attempt to join in sexual acts it also really is an attempt to identify with your own body, to identify the other person with their body, to bring the two bodies together in an attempt to believe that the two persons/spirits are actually joining. This is a body delusion. The physical bodies are all that are coming together, and even their sensations of contact are illusions. Forms, matter, energy, keep individuals separated off at all levels and at all times.
Trying to relate to another brother, a spirit, by trying to relate TO or WITH the body, is almost like you're having a relationship with someone's clothing. If you were to fall in love with someone's jacket and trousers and completely ignore the person wearing them, this would indeed be very strange and somewhat insane. But this is what we do when we relate to people as bodies, completely failing to overlook the illusion of the body, failing to see the real person beyond it.
The ego first established a state of massive lack and deprivation. Its isolating of us made us lonely and in need. It built compulsions to try to join physically, not in an effort to bring us closer together, but in an effort to reinforce and emphasize the reality of the body. Pleasure and pain accomplish the same goal of making the body and illusions of sensations the primary focus. "To sense is not to know", and by focusing on sensations we become blinded by perception of form.
In efforts to bring two bodies together in a special, body-worshipping relationship, we actually necessarily exclude vast quantities of individuals. More is left out than is taken in. Due to the separating and localizing nature of spacetime, bringing 2 bodies together must entail excluding billions. The attempt to make two bodies extra special, psychologically, requires the downplaying and attack upon other bodies. A special body cannot be elevated and idol worshipped without condemning all the rest.
"On this side of the bridge, you see the world of separate bodies, seeking to join each other in SEPARATE UNIONS, and to become one BY LOSING. When two INDIVIDUALS seek to become ONE, they are trying to DECREASE their magnitude. Each would DENY his power, for the SEPARATE union EXCLUDES THE UNIVERSE. Far more is LEFT OUTSIDE than would be taken in. For God is left WITHOUT, and NOTHING taken in."
What appears on the surface to be an attempt to join, is ACTUALLY an attempt to separate. And so the ego's promise of body union in fact leads to an increase in separation, unconsciousness, loss, lack, loneliness, isolation and imprisonment. The supposed freedom produced by sexual union actually produces an increased state of exclusion and illness. With the body as the main focus, the mind is shut out and true joining based in real love becomes impossible.
You could say, in fact, that the attempt of two bodies to come together to join to make a baby, is actual a death ritual. The bodies celebrate their triumph over all other bodies, they worship the idol of death, separation ensues and now there are three bodies. Illusions have given birth to illusions. And while this is much celebrated in the world, the ego does have these underpinnings in its mechanics of what is actually happening.
It's possible, for a time, to still use the body for a holier purpose. Love can be extended through it to others, it can be used to teach, to make the body less real, and to overlook form. To the Holy Spirit, the body actually is seen as having NO function.
"It is still true that the body has no function of itself."
"When it is used only as the Holy Spirit teaches, it has no function."
"It is the dream in which the body functions perfectly, having no function except communication. "
"Healing IS the Holy Spirit's form of communication, and the ONLY one He knows."
Trying to make bodies real, to use them as exclusion devices, emphasizing and believing in and falling into the temptation of the flesh, being deceived by physical sensations not recognized as illusions, believing your brother is a body, etc are all ways that the ego uses the body to keep you from what it promises will be the outcome. The ego guarantees separation, while the Holy Spirit guarantees union.
For a time we can use the body with the Holy Spirit, but not to emphasize bodies. Not to use it as a way to focus on the body or believe it can give us anything. Not to use it to get from others. And not to use it as a symbolic act of exclusion. We are to love everyone equally, and this is impossible at the physical level.
"You cannot enter into REAL relationship with any of God's Sons unless you are willing to love them all AND equally."
"Think not that we can relate in peace to God or our brothers with ANYTHING external."
The entire world of bodies has to be more or less "overlooked". "To forgive is to OVERLOOK." To overlook means to "bypass seeing", to see past and beyond. If we stop to dwell on the physical, our sight is blinded. If we stop to focus on the body, the mind stops extending past it. This produces various forms of illness. If we truly want to have a real relationship with anyone, it has to be a real relationship with everyone, at the level of unconditional love, through mind and spirit.
