O soft embalmer of the still midnight! <br />Shutting, with careful fingers and benign, <br />Our gloom-pleas'd eyes, embower'd from the light, <br />Enshaded in forgetfulness divine; <br />O soothest Sleep! if so it please thee, close, <br />In midst of this thine hymn, my willing eyes. <br />Or wait the Amen, ere thy poppy throws <br />Around my bed its lulling charities; <br />Then save me, or the passed day will shine <br />Upon my pillow, breeding many woes; <br />Save me from curious conscience, that still hoards <br />Its strength for darkness, burrowing like a mole; <br />Turn the key deftly in the oiled wards, <br />And seal the hushed casket of my soul.<br /><br />John Keats<br /><br />http://www.poemhunter.com/poem/sonnet-to-sleep/
