honestly, I cant even imagine that being possible..
I mean, unless someone strapped some vaporizer sort of thing to my mouth and nose so the smoke came independent of my action..
I say this because every time SWIM tried to smoke more than 50mg spice (like, say, 80mg a couple of times), SWIM took a hit, second hit, third hit and already totally off his mind but was able to take 4th hit... he could not physically smoke more (and basically just dropped the pipe or friend took from his hand), and after the very strong trip, SWIM saw that there was even some bit of leftover unvaporized crystals in the pipe... so SWIM felt its really not physically possible for him at least..
as for the ´whats beyond the elves´, SWIM had a couple of experiences where he went to a place that one could define ´beyond´, and there was some very calm space with a buddha-like figure floating in the middle of a mandala.... or something like that... It just emanated a lot of peace and wisdom..
but I suspect there are many possibilities of ´going beyond´, and really dont know essentially which experience is beyond which other one, if you know what I mean...
