Then Almitra spoke again and said, And what of Marriage, master?
And he answered saying:
you were born toghether, and together you sahll be for evermore.(...)
Love one another, but make not a bond of love:
let it rather be a moving sea between the shores of your souls.
Fill each other's cup but drink not from one cup.
Give one another of your bread but eat not from the same loaf.
Sing and dance together and be joyous, but le each one of you be alone,
Even as the strings of a lute are alone though they quiver with the same music.
Give your hearts, but not into each other's keeping.
For only the hand of life can contain your hearts.
And stand together yet not too near together:
for the pillars of the temple stand apart,
and the oak tree and the cypress grow not in each other's shadow.

From " The Prophet" by Gibran Kahlil Gibran
