To thine ownself be true”
I cannot find "to thine own self be true" in the Big Book or in the 12&12. Since it is on our coins, I would think it is in A.A. approved literature someplace. Could you tell me where to find it?
The quote does not originate in A.A. literature.
It is actually a quote from Hamlet
This above all: to thine ownself be true,
And it must follow, as the night the day,
Thou canst not then be false to any man.
The confusion comes in because of what many think of as "our coins." A.A. does not make coins, they come from private companies that often have nothing to do with A.A.
Along the way some company decided to put that quote on a coin, for reasons only they would know. Most of the coins used in AA come from a private company called Wendell's. They have a bit of history on their coins at: http://www.serenitycoins.com/historyrec.html
