It's just the problem with those things, and what i've learnt is this: they're meant to be a shortcut to the ultimate... thing, the plane, or whatever you want to say it like, yeah? It's meant to be: here's your thirty quid or whatever, take me to higher consciousness, please. And it don't work that way, bro. You don't get the full benefit. You've got to work your way up that tree, meaning that that is an allegory which is saying: you can't just fly up to the branches. You get me?
