So, if I think the material world is a manifestation of another, invisible world, how do I talk about this? I am not comfortable with traditional “God language,” although I do like it, because it does refers to a larger invisible wholeness.

I have come upon the language of Fields as a way to make reference to the invisible world, the place where lines of potential wait to guide the shape of things and events as they materialize.
Rupert Sheldrake talks about “morphic fields” as shaping everything. I plan to elaborate on this.
Another body of thought that uses “fields” as an explanatory concept is Process Work or World Work or Process Oriented Psychology. The practitioners of this spectrum of efforts have spun off from Jungian psychology to take a more group-oriented, activist path than traditional psychology. The most prolific author from this group is Arnold Mindell.
