"I remember asking Mal, our road manager, for what seemed like years and years, 'Have you got a pencil?' But of course everyone was so stoned they couldn't produce a pencil, let alone a combination of pencil and paper. I'd been going through this thing of levels, during the evening. And at each level I'd meet all these people again. 'Hahaha! It's you!' And then I'd metamorphose on to another level. Anyway, Mal gave me this little slip of paper in the morning, and written on it was, 'There are seven levels!' Actually it wasn't bad. Not bad for an amateur. And we pissed ourselves laughing. I mean, 'What the fuck's that? What the fuck are the seven levels?' But looking back, it's actually a pretty succinct comment; it ties in with a lot of major religions but I didn't know that then."
