guru meditation n.

Amiga equivalent of `panic' in Unix (sometimes just called a `guru' or `guru event'). When the system crashes, a cryptic message of the form "GURU MEDITATION #XXXXXXXX.YYYYYYYY" may appear, indicating what the problem was. An Amiga guru can figure things out from the numbers. Sometimes a guru event must be followed by a Vulcan nerve pinch.

This term is (no surprise) an in-joke from the earliest days of the Amiga. An earlier product of the Amiga corporation was a device called a `Joyboard' which was basically a plastic board built onto a joystick-like device; it was sold with a skiing game cartridge for the Atari game machine. It is said that whenever the prototype OS crashed, the system programmer responsible would calm down by concentrating on a solution while sitting cross-legged on a Joyboard trying to keep the board in balance. This position resembled that of a meditating guru. Sadly, the joke was removed fairly early on (but there's a well-known patch to restore it in more recent versions).
