This is a truly profound email and I am grateful to receive it. There are times during meditation where the bliss manifests in the centre of the forehead and all breathing 'ceases'. It ceases because the quality of perceiving the empty mind is so pristine and exact that breathing is no longer required. I believe this is death. It is also life. The point is, concepts no longer exist. Conscious awareness finally detaches itself from the breathing mechanism. Breathing only 'returns' when I stir the consciousness in search of the breathing mechanism - then it returns.
