You know that paradox where you start with the statement “This sentence is false”? And if it IS false, then it has to be true? But if it is true, then that makes it false again?
Hinduism says that all paths are equally valid. One of those paths is Christianity. Christianity says that Christ is the only way. Both play an equal role in the paradox as each precludes the other. The only difference is that Christianity precludes Hinduism straight off the bat, whereas Hinduism embraces Christianity into the fray but then Christianity excludes itself, immediately.
This problem – this oversimplification, if I’m honest – itself stems from another paradox. Because really the verse from Hindu Scripture where we get the idea that all paths are equal – “truth is one, the sages call it by many names” – refers to the path, the experience, the practice. Not the dogma. Not what it says in scripture. Which, again, is where we got the idea that “truth is one, the sages call it by many names” in the first place.
But of course even that isn’t the end of it. Because you see, that scripture is Śruti, or “that which is heard.” In short it is scripture that comes from direct meditative experience of the masters. Whereas other Hindu scriptures are Smrti, or “that which is remembered” which when it comes down to it, consists of commentary on the Śruti texts.
So “truth is one..” is not at its root, scriptural, but a self-referential truth.
But even so, in a world of dogmatic distinctions dividing the faiths, Hindus and Christians have been playing a game of “This Sentence is False” for roughly 2,000 years.

This is a great post – despite the ending, which I feel just suddenly stops. Lots of good mental meat here to chew on and once again I’m envious of how you’ve been able to communicate so much so succinctly.
Question: Does “equal” mean “same”?
I think when we talk about all paths leading to the Singular Truth and of how all paths are equal, we took often gloss over the idea (the truth, really) that all paths are equal but very much different. I think you hinted at as much when you pointed out that Hinduism is all-inclusive but Christianity is immediately exclusive, which gets the paradox ball rolling.
The only way it can keep working (the only way it even HAS ever worked) is if Hinduism continues to keep “hugging” other paths even when those paths are pushing away.
Thanks, bhai. I don’t think “equal” does mean “same”. Being a Smarti for example, is not the same as being a Jesusist. It can’t be, because one allows for various “gods” being worshiped equally while, as I’ve said, the other says Jesus is It. The path is not the same but the destination is, even if we picture the destination very differently, Christians vs. Hindus. Being that the destination is the same, all paths to it are “equal.” It’s like 38+70 vs. 92+16. Either way you get 108.
I like what you said about Hindus “hugging” other paths. Good metaphor. Even though it isn’t really a metaphor.
