Peace comes from within. Do not seek it without. It can be argued that peace and happiness comes from the subjective internalised perspective of realizing things could be worse and being grateful they aren't. The alternative view that peace and happiness comes from the objective external perspective of having more and better things than at present, while important for growth, can be a never-ending source of jealousy, dissatisfaction and disappointment. A balance of the two, where people are grateful for what they have while striving for more seems the best blended perspective.

The judgment: You are now before Yama, King of the Dead. In vain will you try to...deny or conceal the evil deeds you have done. ... the mirror in which Yama seems to read your past is your own memory, and also his judgment is your own. It is you yourself who pronounce your own judgment.
Sometimes it's better to be kind than to be right. We do not need an intelligent mind that speaks, but a patient heart that listens. You will not be punished for your anger, you will be punished by your anger
