A fear years ago, I was at an ACIM retreat and we were doing a breathing exercise. I became filled up with some kind of energy, which lifted my "vibration" very high. My mind started to see past the physical and reach out and started to see God BEYOND the veil. In that moment I would've left the entire world behind to be with Him.
I'll skip some details but after that, I was seeing with true perception. The amount of awareness and wakefulness I had was off the charts. Everywhere I looked, still seeing physical objects with my eyes, I saw God. God was in everything I saw and God was in my mind. My mind had expanded in some way, moving up the hologram, to where my ego self seemed dissipated and diffused into the back of my awareness, as though I had no center. My mind somehow pulled back away from the world and I began to feel like I was melting into the background, one with it. I felt like I was becoming Christ.
My awareness for some days after, entailed the ability to see a profound gentleness in everything. Everywhere I looked there was unconditional love, in all things. This love seemed so whole and complete, no matter where I looked, that I felt I had no need to look anywhere else to go find anything. I saw it in a chair leg. In a water bottle. In the shadows on a wall.
People were still going about their business doing exactly everything in the same egoic way as before - nothing changed there, because the body's eyes can ONLY see the physical form of things. But at the same time, there was awareness of a love and presence. I was aware of something that it seemed no-one knew was there, even though it seemed obvious. I became so soft. God was so gentle, so soft and joyous. And he was very, very intimate, which was shocking at first because I had previously always put God far away in the sky and here he was well under my skin.
I also became aware of the higher levels of the hologram, an experience of unity, in which the whole was in each part. All of God was in each object I saw. I therefore recognized for the first time in experience, that even though physical objects seemed to assert that "nothing is the same anywhere" or "there is nothing that is whole" or "the whole is not in any of the parts", here in my awareness I could still see this forms and yet, simultaneously, my mind was aware that a single consistent unified whole was present in all parts, fully, transcending their limitations and differences. This taught me the way in which physical matter is a lie, a deception designed to shut out awareness of God's nature.
I was in an altered state for a couple of weeks. I was very ungrounded. I could barely do tasks because my mind was quite expanded and out of body. Yet each time I did something "grounding", this energy that was in me started to funnel down, and this produced immense joy. Joy would beam out of my face toward others as I started at them very directly, something I had shy'd away from before, recognizing I had no needs, no lack, and that there was only outward extension. Nothing could "come in" to me from the outside. I felt so safe and protected and free from needs. I didn't even want to eat food, it felt so alien.
Gradually as I grounded back into my body my expanded awareness narrowed down, became more focused into and through the body, and I became more immersed in the physical body again. This was like receiving some kind of brain damage. My awareness diminished greatly and it felt like being greatly subdued and suppressed, shut down and locked inside a prison suit. This also stripped away most of the intense wakefulness that I had, which felt like "leaving God", which was VERY upsetting.
This made it impossible for me to have God in my mind, and thus I stopped seeing God outside of me in all things. It seemed God left. I kept trying to find God outside of me because I thought that He was out there, having seen Him there, but I couldn't find Him because I was no longer aware of Him WITHIN my mind. And for weeks this was depressing and infuriating, although gradually I adjusted and was reassured by a few momentary glimpses that God was still with me. Returning to my body felt like a huge isolation. As my eye sight returned to looking out solely through the body's eyes, it was like building a brick wall "behind" me such that I could no longer have any sense of what was there. The body cut me off from awareness of God, and so I got to see first hand just how limiting bodies are.
What I later came to realize was this was an experience of true perception. A state of seeing a forgiven world. It was as though layer upon layer of thick "judgement" had been scraped off the surface of the world revealing an extremely gently held picture of something very lovable. And yet at the same time, the physicality was the same. The appearance physically to my eyes was the same. It was what I saw IN it, in SPITE of the physicality, that I longed to reconnect with.
This is why, for me personally, I know that this physical world is not real. I know how much the body lies. I know how the body's sense are massively limiting. I know how matter lies to try to obscure the holographic nature of God and his omnipresence. I've seen it and experienced the transition back and forth. God gave me a glimpse of awakening and it was the most profoundly directly educational experience of my entire life.
This is why I know first hand that there is something very much beyond this world, a reality which is completely obscured by forms and trapped by bodies. This world is not my home. I have grieved for the "loss of God" and gradually over time use this as incentive, a taste of what's to come, to find my way back to God again.
The attraction to Him was SO STRONG that I would've leapt into His arms in an instant without so much as a consideration for anything else in all the world. We have protected ourselves from remembering just how appealing God is, and why NOTHING else means anything even remotely close to Him. We only block awareness in order to hide this extreme attraction. Otherwise we would awaken in a heartbeat.
