The Buddha quotes, with sources

Hatred does not cease by hatred at any time: hatred ceases by love, this is an old rule.

Even by the falling of water-drops a water-pot is filled.

Health is the greatest of gifts, contentedness the best riches.

Purity and impurity belong to oneself, no one can purify another.

Fletchers bend the arrow; carpenters bend a log of wood; wise people fashion themselves.

As a solid rock is not shaken by the wind, wise people falter not amidst blame and praise.

Let us live happily then, not hating those who hate us!

Let us live happily then, though we call nothing our own!

He who has given up both victory and defeat, he, the contented, is happy.

The fool who knows his foolishness, is wise at least so far.

Self is the lord of self, who else could be the lord?

You yourself must make an effort.
