I had a weird experience last night...I've been working on small circulation in my nightly meditation, and I was sitting there pretty still...felt qi going up my back in waves of sorts from roughly GV8/9 to 13/14 or so...times like that when I do pulling down heavens I feel staticky all over my torso & arms. Every so often I am still reminding myself to return yi to ldt. Anyway, a while after that I had a pretty odd head trip, almost like my midbrain/thalamus (tough to pinpoint exactly, but it was center) was pulsating a bit. The sensation grew almost in a Y shape as if it traveled upwards and out the left & right hemispheres, but once it reached that extent it felt remotely dizzying - but I didnt feel like I was going to tip over...just an odd sensation that's tough to describe...like the feeling that I was turning my head back and forth a couple degrees, almost a remote feeling of...torsion? (not tension though) As if the lobes were gently rotating opposite spins....remotely like the 'rolling' you experience when you've had too much to drink in that you feel movement of sorts but there is none, only it wasnt painful, unpleasant, or disturbing. Interestingly, I was completely still the whole time and the sensation was all brain. I didnt get disturbed by it or anything, my level of awareness stayed the same, yet it felt like my level of consciousness went...deeper, in an ambiguous way. (all observations/recollections after the fact.)
I didnt intentionally do all of that...but about that time I did intentionally bring my attention back to the ldt - after a short while the brain sensation left calmly, I continued breathing for a time, then did my post meditation stuff. (massage, healing sounds)
*shrugs* I feel fine today...though I have been slightly 'out of sorts,' as it were, for most of the week. I havent really tried to discern any meaning from that...quirk, of sorts?
I have been reading a lot about the brain recently, though...in the 700 page zen & the brain book I bought a few weeks ago. Massively complex, addictively interesting...I havent been 'trying' anything though...just keeping my focus on the basics of small circulation...not that there is a 'try'
but perhaps since my subconscious has a lot of...itself? in parsing lately, it might have welled from there.
That experience isnt like one I had a month or two ago, though. I got my breaths very long, about 40 seconds for a complete breath, and I felt some ridiculous stillness to the point where I almost felt like I disappeared, didnt even feel like I was breathing even though I was. After a while of 'trying to do that again' I remembered that you cant wish such states upon yourself...but that was one of the coolest things I've experienced so far.
