It's entirely up to you.
And that's the whole, entire point, is it not?
Personally, I can vouch for the 40x salvia divinorum. But take it sloooow, my babies. Work your way up to the heroic doses required to quite literally meet and communicate with the entity some call The Green Lady. She's very nice, but with her lack of social graces - like, she'll reach inside your head and pull out a handful of endlesslly long writhing snakes, and laugh at your pants-shitting terror - but she really does mean well. Try to remember that while she's turning you inside out and dragging your still throbbing remains through your very own personal fractal kaleidoscopic meat-grinder.
Oops! I forgot to mention that the photograph above is from a recent Washington Times article about how totally fucking awesome magic mushrooms can be at fixing brains that are broken by depression, battlefield trauma, encroaching mortality and all sorts of other crap that more mundane meds just can't seem to get a handle on.
Who'd a thunk it?!
Um... well... me and pretty much everyone I know and love, for starters. And that's a lot of people, people.
Shanti! Shanti! Shanti!
