there are no rules as far as I know of. No dogma nor "church"
and yes it is a personal approach to the issue of worship.
Usually principles evolve into rules. And rules (depending upon given importance) might become dogma eventually. This is why I was interested in the ideas behind this world view, understanding or religion-to-be movement if you like.
Pantheism is a bit like what used to be called Paganism but more comprehensive and contemporary.
Criteria, criteria and criteria: Otherwise how are we going to decide on the level of comprehensiveness and/or contemporary-ness? And mind you, it wasn't an accident Paganism was crashed by new type of religion; there was a need for a brand new mobilization for a brand new social projects of developed agricultural societies. So, what is the social project (where does Pantheism want to see individual/society?), what is the desired mental effect in people's minds?
Most Orthodox religions practice exclusion in some form or another. where by they isolate those that aren't of the faith. Including those that are ignorant of that faith be it a person or an animal.
"Can a dog or a cat know Jesus?" sort of thingo.
where as pantheism is all inclusive taking in the entire universe and all that it holds.
Yes, but question is still there: Can a dog or cat know Pantheism? Some "We" (some humans) giving a new inclusive meaning to universe and all does not necessarily mean that all people will agree on it, let alone cats, dogs and atoms.
It is the atheists' religion if you like.
Hmm, ask an atheist how would they think about this idea after all these clash with already existing religions. If an atheist would need a religion, they would prefer to modify the existing ones rather than inventing new ones I guess. I don't call myself an atheist, I prefer "non-believer". Yet it wouldn't stop religious people to call me an atheist. I don't mind. But ask an atheist about how would they feel about a religion for themselves.
There is no leader, no single divinity except that of the entire universe if one even wants to refer to it as divine.
This sounds like "there is no need at all" to me. You see, when you start to talk about "divine", the problem of representation emerge. Who will tell us what is divine and what is not? If everything is divine (maximum inclusiveness), that includes literally "everything". So the divinity becomes unnecessary; a self-annihilated concept. Something like "Everything is energy"; so? What does it tell us distinctively?
It's tree hugging and mathematics, it's physics and wicca...etc etc
you get the picture I think...
You hope that I get the picture. But I think you would object if you knew what type of picture I got: Why do I hug a tree? To show my emotions and to display my political position against human policies. Yet I kill millions of bacteria when I complete a simple daily task. How does it fit? Does your Pantheism include bacteria as well, or is it restricted to trees only? Mathematics and physics are mind games, tools if you like. They have their own rule books. A mathematician can listen to music or paint a landscape in order to calm his/her mind, do some yoga; but when it comes to the job, none of them are relevant, and or necessary.
My point is this: Your Pantheism has social, moral and maybe political implications (the smell comes from this "-ism"). These things necessarily involves mobilisation of people; and talking about "people" also necessarily includes some sort of "exclusion" (human madness vs everything else). This is not optional, there is no escape.
