Yeats - the path to happiness

"At certain moments, always unforeseen, I become happy ... I look at the strangers near as if I had known them all my life ... everything fills me with affection ... It may be an hour before the mood passes, but latterly I seem to understand that I enter upon it the moment I cease to hate."

-William B. Yeats

"Ever since I have come in the company of saints, there are no enemies, there is no stranger."

- Guru Arjan Dev
