He has entered the Off-State.
Which I prefer over superstitions about ordering dead people to "rest in peace," because brain preservationists want to turn death from a permanent off-state into a temporary and reversible off-state.
Seriously, think about the traditional expression. We use the imperative tense of the verb "to rest," and it sounds like a spell one of our shamanistic ancestors came up with to keep ghosts from bothering the living.

Not so. Neither the expression "rest in peace" nor the longer version "may s/he rest in peace" contains any imperative verbs. (Also, the imperative is a mood, not a tense.)
In the full expression, the mood is optative, not imperative. That should be clear from the examples at this link. It does not express a command; it expresses a wish.
