A few words from 'The Prophet' - Kahlil Gibran

Love gives naught but itself and takes naught but from itself. 

Love possesses not nor would it be possessed; for love is sufficient unto love.

When you love you should not say: 'God is in my heart'

But rather 'I am in the heart of God'. 

And think not that you can direct the course of love, 

For love, if it finds you worthy, directs your course.
