The key to becoming a New Human is to process all of our human stuff
Most new age spritual seekers will try and find shortcuts to this, and some of the bypass techniques will work for a short time, but eventually we all have to face and feel all of our past experiences (good and bad, uncomfortable, and joyful). The soul wants to collect all experiences and it can't do that until we have fully felt them all. And so we are led and guided over and over again to similar experiences until we surrender and feel what we must feel. And it is never as bad as what we think it will be!
Many years ago I was having a particulary emotional day. I remember tapping into something that I had hidden deep within me. Crying and fearful I recognised that this emotion or feeling or belief (whatever you want to call it) was something I desperately wanted to hide from the world (and myself) and that I would rather die than fully face and feel this. I had been suicidal in the past and so recognised that feeling of hopelesness and inner torment and pain, and as it was coming up out of me in that moment I felt ready to acknowledge it. I saw what it was, I heard what that belief was, I felt the shame, the hurt, the heartbreak and then it was gone. I felt like a ton of bricks had been lifted in that instant, and I felt amazing. Moments after this happened I could not recall what the feeling/belief was, I still can't. I can remember the process but not the actual thing that I had spent most of my life burying deep within me so fearful of ever feeling this or allowing anyone else to know it was there inside of me. It must have taken me so much energy to bury this thing.
I can't remember it now because I have processed it.
Once we have processed something the soul absorbs it. The feeling or thought is no longer part of our "human", it belongs to the soul, and this is how our soul evolves. Unprocessed thoughts and emotions just hang around our human causing all sorts of issues. They are like blocks or bubbles of energy which weigh down the physical body, cause physical pain and symptoms, and they create loops of patterns of behaviour which keep us stuck.
Unfortunately our society raises us to avoid expressing certain feelings - to suck it up and get on with things. And so we do, we keep our anger hidden within, we keep our grief bottled up and we even keep our deepest desires and longings buried deep within us. All of this is just wanting to be seen felt and heard.
If we don't process our "stuff" then it just hangs around, we may even try and "throw" it towards someone else and see if they can deal with it for us, or we distract our selves with such busy lives that we don't allow space for anything else to come into our awareness. We try and do anything we can to NOT FEEL.
This is pretty normal human behaviour.
In order to become a New Human and evolve we MUST process all of this. Life will show you what to process and when. The opportunities will present themselves in perfect timing for you if you are just willing. It will be hard, but never as hard as what you think it will be. And even if you think you have "dealt" with something it may come back again and again so you can see it and feel it from a different angle - this is often necessary so we can process layer by layer.
Every time we process our emotions, feelings and past events, we are helping the whole of humanity process theirs as well. The less of this unprocessed "floating" energy that there is in the world, the less drama, torment, instability, abuse and craziness there will be in the world. We focus inwards and take care of our stuff, and the rest of the world does the same.
New Humans who have processed all of their stuff will then be able to instantly process new emotions, events and interactions at the time that they happen creating an authentic and peaceful way of living.
As a spiritual evolutionist I see and live in a different reality to most people.
