Delirium (joking at illness)

I don't want to come, yet suddenly I'm here;
I don't want to leave, yet suddenly I'm gone.
Don't know where I've come from. or gone from, either.
In this there is, of course, True News.
Since heaven can't speak, I'll have to pass it on.
Just wait for old Master Chaos to come back to life.
If I search for myself, I'll certainly find me.
