He who, seeking his own happiness, punishes or kills beings who also long for happiness, will not find happiness after his death.

Resolutely train yourself to attain peace

Some do not understand that we must die, But those who do realize this settle their quarrels.

Let none find fault with others; let none see the omissions and commissions of others. But let one see one's own acts, done and undone.

When you move your focus from competition to contribution life becomes a celebration. Never try to defeat people, just win their hearts.

But if you do not find an intelligent companion, a wise and well-behaved person going the same way as yourself, then go on your way alone, like a king abandoning a conquered kingdom, or like a great elephant in the deep forest.

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.
