Thanks for this, I don't remember reading it in the book!
People often rail against the, "Insane" label or the, "Why are you doing this to yourself?" thing, but it's so true.
Examine thoughts (self.) Examine actions (others and self.) Do they match? Are they leading to serenity or away from it?
If not, that is insanity. Delusion. Whatever you want to call it. I'm a double winner and have to be very careful about my thinking.
