If you hit the sweet spot on LSD or psilocybin or MDMA... If you hit any of those sweet spots... If you experience something like unconditional love on MDMA or you experience self-transcending unity with nature on psilocybin, it's like experiencing physical perfection of a sort that only the most highly-trained athlete would ever touch. You're just dropped into it, and then you lose it again when you come down, but you realize a state like that is possible.
