Yes, at the level you mean I agree that there is one truth. The question is, are we in our embodied-souls-as-humans-experience supposed to or even capable of discerning that truth. I think not by any method. That would mean achieving enlightenment, which I do not believe any human has or ever will achieve. More enlightened, sure, but reach the goal line, no, in my opinion, and any person claiming to be a guru that has and can lead another there, is full of shit.
