"Why would it be superstitious from a materialist point of view? Are you saying that the NEP is not experiential?"
Karma, rebirth, realms, ghosts, gods, transference of merit, protective spells, magical abilities - what about these?
You are suggesting that the NEP may be experiential but Karma, rebirth, realms, ghosts, gods, transference of merit, protective spells and magical abilities are not?
"From a Nietzschean point of view any belief system is exactly NOT nihilism. Nihilism is a loss of meaning. Obviously Buddhism is meaningful to many people."
"Both [Christianity and Buddhism] are to be reckoned among the nihilistic religions—they are both décadence religions—but they are separated from each other in a very remarkable way." (The Antichrist, §20)
Nihilism means the rejection of all religious and moral principles, often in the belief that life is meaningless.
It is a very common tactic among those who wish to promote their own belief system to accuse other belief systems of being meaningless or based on false principles.
I was only referring to making Buddhism a universal teaching. Universal to whom?
I don't know. Maybe this goes back to the question of what is experiential. Maybe Buddhism cannot be true for just anyone. Maybe it is only a viable religion for those who can experience it in full? those who can experience Karma, rebirth, realms, ghosts, gods, transference of merit, protective spells and magical abilities etc etc?
