This is an interesting thread, OP - I've been thinking along similar lines recently.
Thank you to the PP who posted links to Fiona Drake and HAdV - I've had a look, but tbh they sound a bit 'woo' for me (absolutely no offence intended, but the hackles on the back of my neck do tend to rise when somebody talks about their spirituality in this sort of context).
Sorry for piggybacking on your thread, OP, but has anybody ever worked with somebody who is a bit more pragmatic in their approach?
