Hello Jacques, interesting questions and observations. The esoteric notion of a subtle or etheric body could be the first step in widening the scientific world view. I think Kant somewhere says that the lack of a substance that mediates between soul and physical body is a great problem for science. But the etheric body is just that kind of substance. My understanding of its nature comes from Steiner’s anthroposophy. He describes the etheric as a kind of anti-space of “geometrical” or formative forces. However, the notion of “vibrations” seems to me to be a materialistic metaphor that is not really applicable to the etheric. But I may be wrong. Another researcher which seems relevant here is Rupert Sheldrake and his notion of morphogenetic fields, which I imagine as fields of etheric energy or forces. His research has showed the existence of such fields quite plausible.
