I can't say at what level the intention starts, it's pure guesswork. As in my last response, possibly at the level of polytheistic deities.

I've never suggested that God is three in one; I don't know where you got that idea from. If God is defined as the ultimate source – universal consciousness – then that would be a unity.

I have never found universal consciousness. I merely accept it as an idea, because that is what every spiritual tradition says (possibly apart from the Abrahamic religions).
