All that may be wished for, will by nature fade to nothing.

The renunciation of doing harm is the perfection of discipline

Those desiring to escape from suffering hasten right toward suffering. With the very desire for happiness, out of delusion they destroy their own happiness as if it were an enemy

There is no evil like hatred, and no fortitude like patience.

My body, thus, and all my good besides, And all my merits gained and to be gained, I give them all away withholding nothing To bring about the benefit of beings.

All the happiness there is in this world Arises from wishing others to be happy. And all the suffering there is in this world Arises from wishing oneself to be happy.

What need is there to say more? The childish work for their own benefit, The Buddhas work for the benefit of others. Just look at the difference between them.
