and here is an excerpt from Sylvia Boorstein’s book, Pay Attention for Goodness’ Sake:

A contemporary gratitude prayer making the rounds of meditation center bulletin boards reads: “I am thankful that thus far today I have not had any unkind thoughts or said any harsh words or done anything that I regret.  However, now I need to get out of bed and so things may become more difficult.” I am glad to use it as my  “text” for inviting people to recite the Five Precepts out loud to themselves in the morning as they begin the work of their day.  I say, “Maybe we should extend this prayer.  We could add, ‘And since things will surely become more difficult, and since I want to end the day thankful as well, I intend to:

Do no harm to anyone,

Take nothing that is not freely given,

Speak truthfully and helpfully,

Use my sexual energy wisely,

And keep my mind clear.'”
