Yas, God is vein.
Ok. I could accept that as an axiom for the Abrahamic traditions, but what about the East? I don't even know if they have the practice.
Eastern religions are usually more about the individual than the gods themselves. For example, in Hinduism devotion to the gods is just another way of achieving true happiness, and there are other paths to Nirvana that have little if anything to do with the gods. You don't have to jump through hoops to prove your devotion to your gods of choice, because they don't give a shit and you're mostly doing it for your own sake.
Everyday I'm believing less and less that Yaakov is a historian. To get a BA in history you have to take world, ancient, European, and American history courses so he should have basic knowledge of most cultures/histories.
Like Tausami said Eastern religions are more about the individual than paying homage to a god. Buddhism, for example, is about achieving Nirvana through meditation and releasing yourself from all physical and earthly desires. Buddha himself is not even a god as we know them. If you consider meditation prayer than they tend to do that in the morning and at night and for as long as they wish.
Other Eastern religions allow for small shrines for a house/family protector. Since it's not monotheistic they pray to whichever god that's relevant to their situation but there's no strict rule that I'm aware of.
In ancient Chinese religions your ancestors would be your gods/protectors and that is who you would have prayed to with state "religions" being more social/political institutions like Confucianism.
