Mantras for riding the MUNI

So I've been riding the MUNI to work every day, and for the past week I've been reading Pure Heart, Enlightened Mind. It's helping me stay remarkably sane, so I thought I'd share my secret: I repeat little chants over and over while breathing deep. For your use, I offer them here. Repeat a chant during the following circumstances:

When the train is stalled for no particular reason in the tunnel:
My mind is as still as the subway train.

When the stairs jam upon raising or lowering:(emitting a very strong beeping sound)
The nightingale's song is sweet to my ear.

When the train screeches to a halt and people fall down:
I am one with the movement of the world.

When the driver makes an unintelligible announcement:
The voice of Buddha brings me peace.
