This got brought up at a teaching I went to, I hadn't heard about it because I don't read stuff like this.
Yeah, he says some funny stuff about tetrahedrons and other new age sounding stuff, but it seems that through acting, Jim Carey had an initial experience of Anatta. Amusingly, to most commentators, he appears to be "crazy", and almost every article I read just dismisses him as such.
For myself at least, it was just such an experience that solidified my interest in Dharma, mine came from working at weddings all the time, one day I just couldn't get over the "this is not real", "this is like a play" feeling when I was watching people dance, hobnob, put on airs, etc.
Anyway, despite being kind of disjointed, I felt like his words actually had some wisdom, and he says some things that are -exactly- what these people need to hear.. and the reaction to them says a lot about our society. Their reaction to his words really makes clear the vapidity of celebrity culture.
Later on someone asks him about the interview and he says:
‘Who’s Jim Carrey? Oh, he doesn’t exist actually.’ There’s just a relative manifestation of consciousness appearing, and someone gave him a name, a religion, a nationality, and he clustered those together into something that’s supposed to be a personality, and it doesn’t actually exist. None of that stuff, if you drill down, is real.”
