As always, this is all my observations and opinions.
I see it as part of the wider ignorance of Hinduism, our gods and practices, their origins and a condescension and patronizing of Hinduism, India and Indian culture. It looks like I’m reading more into this than there is, but this article was just the match that lit my fuse about the subject. And then there’s the ignorance of the other pantheons by these scholars, which I believe is rooted in the perspective of the Abrahamic paradigm.
The universalism I’m talking about is not the same universalism that Vivekananda, Ramakrishna, Gandhi (love him or hate him), et. al. talked about. Their universalism said all religions are equally valid (for their followers), which I agree with. They didn’t say all religions are interchangeable, ancient sources and origins notwithstanding. This universalism diminishes the uniqueness of each of these religions. I see it as a lumping together of them.
Some people say the gods of different pantheons are the same gods seen through different cultural and linguistic lenses. I don’t think that’s wholly false or wholly accurate. There probably is some overlap and equating one with another. And then there isn’t ... I think there is less correspondence between pantheons than people think. Almost all cultures have similar archetypes... a sun and moon god/dess; a warrior god or goddess (defensive war, Ares is about the only war god with a gratuitous blood lust, and lust for war for its own sake); a god/dess of arts, wisdom, learning.
However, apart from the archetypes I don’t see any connection between Saraswati, Apollo and Bragi; a sea god, again I don’t see any connection between Varuna, Aegir and Rán, and Poseidon especially in temperament; there are no hunters in Hinduism like Artemis, Ullr, or Skaði. I see little to no correspondence to the Vedic gods in any other Indo-European pantheon. The gods we worship today in Hinduism are puranic not Vedic. And the Vedic gods are the original Indo-European gods. The list goes on as far as I can see.
The New Age movement has only served to amplify it. I have frequented other spiritual and religious forums over time. I cannot tell you how many times I or other followers of a particular path have told people if they want to include gods of other pantheons in their worship, do so in that pantheon’s cultural context.
People like the Hindu gods and have asked if it’s ok to worship them alongside the Norse gods, for example. Maybe yes maybe no. Odin takes no sustenance except for alcohol. Odin is duplicitous and deceitful, using any means to achieve his goals. For someone wanting to worship any Hindu deity, is that really the example one wants to follow? Frigg alongside Tridevi, Hera, Juno, even Kali? Sure, all compassionate and resourceful mothers.
I worship Thor. I keep him separate from other deities though. There is really no reason to do that except that his statue is a completely different style that doesn’t aesthetically fit in my Hindu shrine. He accepts any offerings... non-alcoholic, vegetarian because he’s a chow-hound. So I could do a puja for him. Thor is not unlike Lakshmana (quick and fiery temper but quick to cool down, loyal and honest to a fault, compassionate), Hanuman (inhuman strength, honest, compassionate and loyal). And they reflect my personality and characteristics, especially Thor and Lakshmana. So it’s a fit in my case.
So on this we’ll have to agree to disagree.
