To be perfectly honest, I havenÝt really thought about what it feels like, as much as I have been enjoying the sensation.
I don't now about 'being breathed' - but in a way, I guess you could call it that.
I'll try to describe it: It feels like a slow vibration within me. The vibration doesn't feel like me - but it doesn't feel like it's not me either - if that makes any sense?
My awarness can float freely around this vibration - and even 'see' it, or feel it in the world, in the swaying of trees, or the pulsing of traffic, or in the rythm of the way people walk. Also in the connection between the words and small movements of facial-muscles when people talk.
Words don't really do it justice - but it's real cool
It sounds a lot like the way I noticed feeling - and I identified it as being-breathed
- very shortly before my experience of enlightenment. It was impossible to miss. A whole new dimension to the transparently automatic act of breathing.
I would say you are right, about being on the verge of something spectacular.
Here's something I discovered, unexpectedly, without which all would have been for nothing:
At the very brink, when you've taken yourself as far as you feel you can go, then give it up, retire, dispense with any desire to 'get somewhere'.
Shut down and vanish. Poof
