No, there are no different mountains, there is only one mountain and different paths to its summit.

There are no different enlightenments. Buddhist enlightenment, Hindu enlightenment, Advaita enlightenment, even Christian mystic union - they are all the same. If they are not the same, it’s not enlightenment, not yet. Please continue your spiritual work.

At a certain point of the journey, all paths merge together into One Great Path. Enlightenment lies well, well beyond that point, well beyond the point where the difference between all spiritual traditions makes any kind of sense whatsoever, when all their arguments become absurd and seen to be purely egoic, well beyond what any spiritual tradition could describe.

No spiritual tradition can describe enlightenment, it is not even a remote possibility. Enlightenment is indescribable, there is nothing to say about it. All spiritual traditions only describe the path to enlightenment, at varying degrees of accuracy and completeness. Buddhism does it better than most, as a spiritual tradition, Buddhism is pretty complete. But it’s also perverted and misinterpreted by the ego just like any other tradition. With the death of the person who started the tradition, it is almost a surety that it will happen.

But no spiritual tradition can describe enlightenment itself.
