“A totally nondenominational prayer: Insofar as I may be heard by anything, which may or may not care what I say, I ask, if it matters, that I be forgiven for anything I may have done or failed to do which requires forgiveness.  Conversely, if not forgiveness but something else may be required to insure any possible benefit for which I may be eligible after the destruction of my body, I ask that this, whatever it may be, be granted or withheld, as the case may be, in such a manner as to insure said benefit.

Amen.”
