Pantheism is the expression that all things are God. I am God, you are God, the trees are God, the sky is God, your desk is God, all of existence is God. There is no relationship between reality and divinity besides reality is divinity, we are divine. God is the action.
All of existence is God as one single expression. We are all one, we are all interconnected.
All movement of air, physical objects, qi energy, all of it is within the pantheistic wave vibrational system we know as psychedelia. It's all the same, it's all the same concept, reality is a psychedelic hallucination. You don't understand until you understand, it's psychogeography.
Baruch Spinoza pretty much only hit the initial concept and popularized it. It's better than anybody was doing at the time, he did very good, he gave the world a concept to think about, however, no, there's nothing to philosophize around pantheism, it simply is what it is.
There is only one substance. That substance is God. Everything else is a mode of that substance. ~ Baruch Spinoza
God does not act according to freedom of the will. ... From the nature of a triangle it follows from eternity that its three angles are equal to two right angles. ... Men believe themselves to be free, because they are conscious of their actions and ignorant of the causes by which they are determined." ~ Baruch Spinoza
That's pretty much the best way to put it. That's all you really needed to do. But, obviously, if that's all you did nobody ever would have listened to you.
However there is emanation, there is a semi-deliberate flow of production. There is a metaphysical hierarchy, we do place humanity as more important than the sun it revolves around. Within dualism, you quite significantly blurred all of your concepts and mushed everything together, yes your mind and your body are interconnected, no you don't place them within the same framework, it's very trippy, very very trippy, very trippy thing to think about, now you just made all of reality into a big block of dull thud.
