Which is the best love poem ever written?

Sonnet 116 by Shakespeare This is my favorite poem: Splendour in the Grass What though the radiance which was once so bright Be now for ever taken from my sight, Though nothing can bring back the hour Of splendour in the grass, of glory in the flower, We will grieve not, rather find Strength in what remains behind; In the primal sympathy Which having been must ever be; In the soothing thoughts that spring Out of human suffering; In the faith that looks through death, In years that bring the philosophic mind. -- William Wordsworth The above poem pertains to looking back on youth and realizing you can never recapture it, but, as an adult you can learn from the sorrows, heart-breaks, the feeling of love, but, we should never linger or grieve over the loss of our youth but find strength from it and indulge ourselves in the memories until our death.
