It's funny you say this, while at the same time deriding mysticism as "sentimental and worthless". When actually this process of observing how "you as an experiencing being are constituted" and "seeing how everything fits together" is what can lead one to the realisation that everything is connected, separation is an illusion etc and that realisation if experienced and seen "all at once" as it were, without all of the words and concepts trying to translate it (since those break up the cohesiveness of everything) is exactly what a mystical experience is.

"none of the answers proposed by any and all of the major religions and philosophies and gurus has any bearing on the subject because they haven't bothered to look at the facts" - so really you're saying that all of the millions of spiritual seekers in history, and all of the philosophers that have ever lived, NOT ONE has "bothered to look at the facts" and has any view that is valuable or has any bearing on what you believe the truth of reality to be?

Wow. Bold claim. What is the truth of reality then, oh wise one? If no philosopher or spiritual teacher has ever realised or articulated it before, aside from you?
