you couldn't show compassion to others unless you have compassion to one's self. The note refers to specifics on how you treat yourself when you are in a dire situation. Eg. Do you resent yourself or do you self attact, regret or compassion or self-critic. Do you hate yourslef? It starts by this situation that you ask yourself, how would I advice a friend if my situation happened to them? By treating yourself the way you treat a true friend is a start. Btw, there is no straight answers, all of these take a lot of practice. ❤️
