Eric M W:
The "flow" of sensations could possibly be A&P. A&P isn't always big or dramatic, sometimes it is fast and subtle. If you can say more about the "flow" it would be helpful.
Your current symptoms do fit DN descriptions. Best advice is to continue practicing, sit with the negative sensations and note them diligently, accepting them for what they are.
Thanks Eric.
When starting the vipassana body-scans, I could rather easily feel some basic senasation on every part of my body -- the touch of the T-shirt cloth, a bit of cold air, the points of contact with the cushion and the florr, etc.
Quickly (second day of vipassana, IIRC), at the beginning of a scan cycle, I felt a "tingling" at the very top of the head. A bit like the "ants" one can feel in the legs when blood returns after being cut off for a while -- but without the pain / unpleasantness. The tingling sensation was agreeable -- in the sense of "nice", not climaxtic. It expanded slowly from the very top of head to the neck in 10 - 20 sec (difficult to be sure about timing). Imaging warm honey poured on your head.
I could recognise a "vibrating" feel too -- quite fast but not too fast -- 5-10-ish times per second ? -- actually I remeber thinking at the end of the session "Are those the vibration mentionned in MCTB?" -- Another interesting characteristic was that absolutely all areas of my scalp were sensing this and that it was slowly moving by itself.
This type of sensation stopped at the top of the neck / around the jaw and just below the ears. On the nex and top of shoulders, just the "basic" sensation of clod / warmth / air / cloth.
Tingling and flow on the arms, and occasionally torso -- A couple of times in the legs, but some pain in the knees and feet overwhelmed any subtler sensations. On a few occasions, I had that flow not only one the skin, but also "inside" the body mass.
I'll take your advice to continue practicing and incorporate the DN sensations into the practice. Better face the situation clearly -- but maybe not too fast / too frequently before I understans better how to manage the side-effects in daily life better.
Many thanks --
