From the poem "Recommendation" by Thich Nhat Hanh:

Alone again, I'll go on,
with bent head, but knowing,
the immortality of love,
and on the long rough road,
both sun and moon will shine.

Promise me, promise me this day,
while the sun is just over head,
even as they strike you down,
with mountain of hate and violence,
remember brother,
man is not our enemy.

Just your pity, just your love,
invincible, limitless.
Hatred will never let you face the beast in man,
and one day when you face this beast alone,

your courage intact, your eyes kind,
out of your smile will bloom a flower,
and those who love you will behold you,
across ten thousand worlds of dying, of dying and birth.

Alone again, I'll go on,
with bent head but knowing,
the immortality of love,
and on the long rough road,
both sun and moon will shine,
lightning my way.
