Those are wonderful info, thanks guys.
I feel where the problem is, because I try too hard to just think about one fixed point in my nose, and that's not being gentle to myself. No wonder the mind rebels.
So we are allowed to feel the breath flowing anywhere in my body, and even to become 'aware' of the surroundings, and not 'focused' on any one thing.
That means when I can feel being at present, and can hear soft noises outside, but without any reaction in my mind (just hearing, not listening, no perception, no feeling), then I should still be on the right track.
But if we can have the link to that talk, it will be good.
