This world has no purpose and only the next world has meaning is the definition of nihilism. We must have a purpose or we will compensate with narcissistic tendencies. This is obvious in our modern open age.
The only reason occultists would agree to Christianity is that, because of the golden rule, we are aware there are other people. That is the only good that Christianity does.
Let me repeat: That is the only good that Christianity does.
By being aware of other people, people can not be narcissistic.
The vacuum of nihilism would then be filled by anything, and anything is better than nothing, our natural condition.
Without narcissism, we would not have the openness of the modern age that is destroying our advanced civilization.
If anybody thinks our society can have openness and equality, they are fooling themselves as these are, by their nature, unnatural.
