According to the Life of the Elder Moses of Optina, a troubled monk visited the elder, seeking his counsel.
“Batiushka,” he said, “there is a thought that is bothering me a lot.”
“And what does your thought say to you, brother?” asked the elder.
“Well, Batiushka, my thought says to me that you’re not doing this right, and you’re not doing that right. . . .”
“My brother,” he said, “tell your thought that this is none of its business.”
Simple. Serenity suddenly settled over the monk, and he left the elder relieved.
I don’t know if you can use that, but it amused me.
