I discovered this poem in an anthology of 123 poems from around the world that you have to read. To me, this poem perfectly describes the essence of love. Although, I have to admit the English is not that easy to understand. But then again, neither is love…
If thou must love me, let it be for nought
except for love’s sake only. Do not say
‘I love her for her smile—her look—her way
of speaking gently,—for a trick of thought
that falls in well with mine, and certes brought
a sense of pleasant ease on such a day’—
For these things in themselves, Beloved, may
be changed, or change for thee,—and love, so wrought,
may be unwrought so. Neither love me for
thine own dear pity’s wiping my cheeks dry,—
A creature might forget to weep, who bore
thy comfort long, and lose thy love thereby!
But love me for love’s sake, that evermore
thou mayst love on, through love’s eternity.
Elizabeth Barrett Browning
