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.
Gautama BuddhaComparing oneself to others in such terms as "Just as I am so are they, just as they are so am I," he should neither kill nor cause others to kill.
Gautama BuddhaHow easy it is to see your brother's faults, How hard it is to face your own. You winnow his in the wind like chaff, But yours you hide, Like a cheat covering up an unlucky throw. Dwelling on your brother's faults Multiplies your own. You are far from the end of your journey. The way is not in the sky. The way is in the heart. See how you love.
Gautama Buddha
