 I'm not saying all religions are the same, they are different. Their doctrines and beliefs are different, some believe in one God, others believe in multiple Gods or no God at all. There are many paths up the mountain, but the ultimate endpoint is the same. Okay, but you said it yourself, how can the endpoint be the same? First of course, we have to determine what the absolute truth is. Within Islam, the absolute truth is God. The way that those mystics describe it, they're speaking about God as well. So now, if the Muslim engages in mystical experiences, for example, within Sufism and reaches the point of full understanding that God is one, he actually confirms he is Islam. But what if a Buddhist gets enlightened, quote-unquote, and witnesses that one God? What does that mean then? That of course implies that Buddhism is absolutely wrong, because Buddhism proposes that there is no God whatsoever. The same applies of course for Hinduism and Christianity that proclaim that God is not uniquely one.
