This resonates very much. I was obsessed with enlightenment since the moment I had the first aha moment. Fast forward a few years of really intense dark night of the soul, this year the process has become 'physical' and full time. The tightness you are speaking of, I feel it very intensely on my chest (and all blockages on chakras, but chest the worst), a cage/wall/knives/congestion and moving slightly and processing never ending trauma/emotion both personal and what seems like the whole damn trauma of humanity (I think I had too many lifetimes lol and really hope this is a last one) It's been rough to say the least, my body is so worn out, I so wish the heart would ease up, it's been there since January, like 'self-exorcism' on all levels.. The mirror/shadow/projection also always there this year, every experience, interaction served as a mirror, every singe thing triggered, extremely sensitive, I was conscious of it, but hard, because almost no outgoing energy or creation, all back at me to expose, lots of defense layers came out through that, a lot of times, i would already see what wound is being triggered, so I would want to go straight there, but eventually still had to go through a dance of defense/anger, cause that layer was tightly protecting the wound. The one thing I can say clearly is that when the soul/god is calling, you have 'less choice'. Like parts of me that want to do/say/act certain way that I know is coming from a wound, I have zero energy to do it (like clean up so I feel 'productive' and appease the shame of 'lazy'), so I don't until that wound/belief is so annoyed that it comes up to the surface to see what's up.. So I see how this is working, but man it takes everything.. And meditation, I enjoyed it at the start of this, now i can forget about it, too much physical pain and when i lie down, purging and crying comes up immediately, I manage to relax sometimes though for a few seconds and then I feel downloads through Crown..
