If all beings are both physical and non-physical I don't see what is 'grounding' any being in either one. Please explain.
Not everyone accepts this notion. Greeks being the perfect example did not believe in the spirit as a whole. They believed the Gods were physical beings who although mortal could die and perish.
You mean the "My-God-can-beat-up-your-God" debate? I'm not sure if you are aware of this, but some of us aren't participating in that debate.[/QUOTE]
No I do not mean "my god can beat up your god". That is very far off basis. I mean the debate on formless god or physical god. A physical god as is often depicted by Greeks, Romans, Hindus and Wathaniyya Arabia has sex (meaning he is human), can be killed (meaning he is not truly immortal), has finite form (meaning he is not powerful), and intervenes in a human fashion (meaning he is only human and powerless).
Chronos the all mighty Titan was imprisoned according to Greek view and castrated according to Roman view. God was castrated and imprisoned essentially. So what sort of god is this? According to rival hindu sects Shiva was cursed and so was Brahma. Neither of these gods sound very powerful. They had wives, had sex, bore children, made mistakes and were not perfect. Shiva killed his own son not knowing it was his by mistake leading to the Ganesh mythos. All of these cultures made god human by giving him form and removed the purpose of god.
Would you really worship a god who is just as pitiful as a human being? This is why Hindus reformed their religion so many times because after later understanding they realized they were diminishing the definition and purpose of having a god in the first place. This lead to inclusive monotheism amongst various sects and the rest is history.
