At the core all religions state the same. The problem is the "guru/rabbi/priest" interpretations.
If you dig deep enough, even all the mythology and the world creation myths are similar. It may not seem so, for ex. in abrahamic trio with "one God" and many Gods of Greeks/Romans and Hindus, butt...
If you really dig deep, all the info is there.
i dont think it is accurate that all religions are the same. there seems to be few other widely believed things that are less true than this statement.
if you look at the view of enlightenment between buddhism christianity hinduism and Judaism it is pretty clear that they are not the same and that they reject one anothers EXPERIENCE... not the words about the experience... but the experience itself.
there are some profound similarities but they have been overstated quite irresponsibly. buddhism and judaism represent the most divergent and wildly opposed states of enlightenment.
buddhism says that if there is any sense of self separate from the other you are not enlightened. even jesus experience does not quality in the buddhist view. buddhism also states that there is no self and there may be no god.
judaism says if you lose that sense of separation between god and self even for a moment you have entered heresy. there is a god, there is a self, and they are NOT the same thing nor even remotely equivalent. this is a description of the EXPERIENCE of enlightenment for jewish mystics and it is not just a language difference.
not only are the ENDS not the same but the MEANS are also very different. i dont teach meditation but i am qualified to do so in the christian tradition and i can tell you that most of what buddhism and hinduism teaches about meditation is completely incompatible theologically and practically with the christian traditions approach and theology.
it seems like the only people who claim all religion is the same and that everyone who is religious is wrong about this fact are those who have have very little knowledge of the various religions, produce no saints and provide no reliable repeatable means of producing enlightenment in others, and who themselves rarely have a deep penetration into even one tradition. these people seem to me to be the leaste qualified human beings on the planet to make these kinds of evaluations.
the fact is there are very important similarities that should make us feel a kinship towards one another but also many very important distinctions that ought themselves to be celebrated in the spirit of appreciating the beauty of diversity of spiritual experience and some would argue the innate subjective nature of it even though it seems non subjective when it is experienced.
