What is your signature line supposed to mean?
The illusion of separateness is the foundation of human suffering.
It's a Buddhist thing, if it needs explanation, you wouldn't get it anyway.
Ponder it and see what you come up with.
So anyway, what are you, a genius or a magician?
In that context, it actually means "genie". It's a line from a movie, like the last couple ones (all from the same movie, matter of fact). The Devil and Dr. Fausto are having a couple drinks at a party and Dr. Fausto asks the Devil if he can make a wish for someone [else] to take care of his assistant, Julia. Fausto gives the Devil a hard time for saying "don't worry" instead of "granted", and then starts to walk away. The Devil asks where he's going and Fausto replies: "Take a [censored] guess, aren't you a genie?" Then the Devil says: "Genies never guess. Those are magicians." It's kind of dry humor.

The Buddhist thing isn't setting anything off, so I don't want to strain myself. If Buddhist rules are that I have to come up with an answer for myself in order for it to make sense, I think I've already got that part down. I'm curious why people have a fondness for referring to things as "illusions" though if they carry such a punch. "Hallucinogens" can really be a misnomer too in a lot of senses. Just my two cents.
