Hindu here, from VA, USA.
Went to a Lutheran School for elementary school. But born and raised Hindu, and still call myself one, though I have personalized my religious and spirtual views to where I’m not really sure what it could be properly called (Perhaps a Spirtual Hinduism).
But yes. You are correct in your initial point- Vishnu (or any incarnation or piece you choose)= God= G-d= Allah. Hindu can be considered Monotheistic or Polytheistic depending on how you wish to split your hairs. Then again, I also feel that if God doesn’t exist, I’m sure it could somehow fit this. ((Because I also tend to view Universal constants of this Universe or to put it simpler “SCIENCE” = God too, but that’s just ME talking, and not the Hinduism in any way- just a belief in a greater order/plan in the universe (Hell, God=Entropy in my book)).
The way I’ve always liked it best was from some Hindu text or another- ((MY interpretation of it, YMMV)):
Spirituality in this lifetime(s) is a mountain. There are many paths up the mountain, and people may choose whichever way they wish. In Hinduism, the mountain cannot be so easily climbed in one simple life, it takes time and trials and many times of patience and learning. Yet, each time you can attempt to climb the mountain, and try yet again- the same way, or a different path if you choose. Yet, if you come back not as a Hindu, that’s fine, you still have the mountain in front of you, and whichever path you choose, as long as you do your duty, you have not failed in Hinduism. Some may choose to deny the mountain, and others may simple stay at the base (Basecamp Party!! Gotta love those Agnostics too!), but it does not matter what path one chooses, for at the top all paths converge. Thus, be kind to others, and respect their choices, for they are fellow travelers in this life, just like you- even if they choose a different path or way, the outcome will still be the same.
Now. If you believe God is the top of the mountain, or heaven is, that’s your prerogative. I do not claim to know what’s at the top of the mountain. Maybe it’s something as unknowable as Duty, or maybe it’s aliens, or maybe it’s just Morality, or maybe it really is understand God. :shrug: I do not know. But We’re all just traveling together, so that’s my view on the matter. I personally think it’s doing your duty, and just living your life positively regardless of your faith. I don’t really care what your religion is, as long as you treat others well and with kindness, and don’t force your beliefs onto others (but that’s my personal view popping in there. I’m sure stricter Hindus will have a different idea of what’s on top of the mountain).
But again, I do not know, and i find the metaphor can work well for the religious, the non religious and all those in between, and pretty much is why I try to respect all 3 branches of the same thing.
Hope that helps.
