Man would have both a stake in the field-like collective consciousness and also as an individual with self-will beyond that. "Beyond" entails beyond the field, beyond space and time - e.g. his non-corporeal soul/spirit.
Here's the question I'm pressing you on: If there are two (or more) non-corporeal, non-spatiotemporal human souls, how is that they are two (or more) and not just one? If they possess no physical characteristics (or relations) at all, and no spatiotemporal locations at all, how can they be distinct?
I have other questions about your views, but this individuation question is the one I'd most like to hear your answer to.
Best regards...
If you cannot, then you and I are individuals. If you can, then you and I are not individuals, but one.
Hint: the Scriptures speak of several instances of oneness where this is possible. Oneness in Him, with other believers and with a spouse - all of this is the same "mystery" (Ephesians 5, I Cor 2, John 15-17, Romans 8, Col 3:3 and I Cor 12)
