Spirit and matter interact, or intertwine. According to the Gnostics, spirit is trapped in matter and needs to break free. According to Paganism, matter is good because it is infused with the Divine; and in mainstream Christianity, matter was originally good because created by the Divine (but then was corrupted by the Fall, it seems, depending on which tradition you ask).
So is the aim to break free of matter, or to infuse it with ever more spirit? The aim of the Jewish practice of Tikkun Olam is to repair the shattered vessel(s) of the Qliphoth. To me, it seems that the aim is to restore matter to its Divine status by infusing it with more consciousness - as Jung put it, to bring unconscious material into the light of day. This happens as part of a collaborative effort between humans and the Divine.
