OK.
More often than not, it's your ideosyncratic use of terms highlights differences and distinctions between us that might or might not be useful/accurate. I certainly don't see the cosmos as 'an amusement park' and I find that term telling in terms of how one perceives the world. If I were being literal I'd say I don't see the world as a place created for my entertainment, but I'm not so sure that's how you mean it?
It seems to me the differences between us boil down to what the Japanese would speak of as tariki and jiriki, both terms derived from Japanese Buddhism.
Tariki: 'other power' or 'outside help'
Jiriki: 'one's own strength'
What distinguishes them is where the focus lies — the former with 'the Other' and the latter with 'the self', yes?
The Abrahamics are fundamentally tariki through-and-through. That's not to ignore jiriki, indeed the emphasis is on jiriki towards tariki. I'm not sure Unity has any dependency on tariki at all.
The development of Unity, it seems to me, in looking at wiki's biography of its influencers, is the increasing focus on the mind — this from Quimby and Fillmore — in which the mind is positioned centre and God becomes increasingly abstract, in the sense of what's the difference between god and the 'inner self'?
