Two souls permanently becoming one...

[zenmaster]

Oh, I do have another thought towards the topic as well. I can conceive that it would be possible to share the experience of a single identity by multiple souls without losing the individuation of those souls but through their agreement to all "play the part" together as a team. I speak of this with some personal relation.

If you carry an agreement to play the part then you carry the idea of separation and the conditions with which you participate. So no unity there.
