Yes when I don't focus on the breath at all I feel much more comfortable. From the instructions in a book by Ajahn Chah he mentions the breath is the only thing you need to focus on, yet to me this seems more like samatha than Vipassana? I've heard very different instructions as to what Vipassana actually is.
Anyway I try not to force my breath, rather just let it be natural, but the sensation I get on the outbreath is one one of vulnerability to my neck. Maybe I am too tense. Do you reckon I should try and do some muscle relaxation techniques before I sit?
"The original heart/mind shines like pure, clear water with the sweetest taste. But if the heart is pure, is our practice over? No, we must not cling even to this purity. We must go beyond all duality, all concepts, all bad, all good, all pure, all impure. We must go beyond self and nonself, beyond birth and death. When we see with the eye of wisdom, we know that the true Buddha is timeless, unborn, unrelated to any body, any history, any image. Buddha is the ground of all being, the realization of the truth of the unmoving mind.” Ajahn Chah
