DMT is the most powerful hallucinogen there is. If it gets stronger than that I don't want to know about it.

The human imagination, which is our great glory, has grown so powerful that we can barely unleash it on the surface of the planet.

...the mind is more powerful than any imaginable particle accelerator, more sensitive than any radio receiver or the largest optical telescope, more complete in its grasp of information than any computer: the human body- its organs, its voice, its powers of locomotion, and its imagination- is a more-than-sufficient means for the exploration of any place, time or energy level in the universe.

I'm not trying to sign people up to a creed, I'm much more interested in the people that disagree. These ideas are powerful but this isn't mysticism in the ordinary sense to be protected by mumblings about faith and all that. This is the real thing.
