Text choice for the wimple embroidery

I have decided to embroider the serenity prayer on the wimple.

It is a prayer that would have been spoken regularly 19th century nuns.

I chose it because it isn't derisive but it does encourage reflection for me about "What is in my power and what is not". "What am I responsible for?"

It is ambiguous. It resonates with me as a kind of universal wisdom. It feels more like a mantra than a prayer. Are they the same thing?

I like that as a verse, it is still alive and relevant today, even in non ecclesiastical contexts. For example it is used during Narcotics Anonymous meetings.
