Sure..
First off, Iøm panentheistic, as opposed to panthiest. I don't know if you call yourself a panthiest, but what you are talking about, seems the definition of pantheism.
Dualism is not illusion in entirety, it's an aspect of it, //a unit, or part of the illusion that we create, or are faced with, by necessity. It would be difficult to quantify that 'amount', of dualistic illusion...it's alot. You say the ''I'', is an illusion, but i do not think that the ''I'' is apparent, in the first place, to be observed //who is observing//. The ''I'', therefore, may not come up lol , for all practical purposes. Anyways, that's a basic explanation of the usage of the words, that I'm using in the dialogue.
