After more than 2 weeks of deep meditation (20 min twice a day), I found last week-end that the pressure in the forehead was much more bearable.
It has not disappeared, still there but much, much more smooth and diffused. It is now located in the whole skull, not concentrated in a single point, and that's a relief. Almost pleasant or galvanizing sometimes.
So I felt confident and three days earlier, I was thinking I could introduce SPB again, just 5 minutes to see where it goes. First i was afraid, i was petrified it was OK, not very deep nor powerful. The third time I tried to make my breath very deep and slow, and the extatic feeling rises from perineum.
DM after that SPB was delighfuly profound, the bodyload was very pleasant. After some rest though, I felt quite nauseous, and my forehead was pounding.
The day after I immediately paid for my hurry, with one of the worst pressure in forehead ever. I could not manage to concentrate on anything at work, and got very angry and irritated for nothing.
That day, I came back to DM only, and yesterday I was relieved from too much pressure once again. I'm truly amazed how fast I react to my practice.
Yesterday I did DM only again, and today I feel so much better, the pressure is diffused and almost pleasant, and my mood is far better than it was 2 days before, or even yesterday.
So I'm gonna stick to DM only for a few weeks, and I will try again SPB once in about 2 months to see if I'm ready.
