Love, romance and relationship quotes for your soul: 'The first duty of love is to listen.' ~ Paul Tillich 'Love can be understood only from the inside, as a language can be understood only someone who speaks it, as a world can be understood only someone who lives in it.' ~ Robert C Solomon 'I have been astonished that men could die martyrs for their religion - I have shudder'd at it. I shudder no more. I could be martyr'd for my religion. Love is my religion. And I could die for that. I could die for you.' ~ John Keats
