And in the most famous passage in all his poetry he sings of Death as of a mistress. 'Life, like a dome of many-coloured glass, stains the white radiance of eternity.' 'Die, if thou wouldst be with that which thou wouldst seek;' and he sees his own soon-coming death in a rapture of prophecy, for 'the fire for which all thirst' beams upon him, 'consuming the last clouds of cold mortality.' When he is dead he will still influence the living, for though Adonais has fled 'to the burning fountains whence he came,' and 'is a portion of the eternal which must glow through time and change unquenchably the same,' and has 'awaked from the dream of life,' he has not gone from 'the young dawn,' or the 'caverns in the forests,' or 'the faint flowers and the fountains.' He has been 'made one with nature,' and his voice is 'heard in all her music,' and his presence is felt wherever 'that power may move which has withdrawn his being to its own,' and he bears 'his part' when it is compelling mortal things to their appointed forms, and he overshadows men's minds at their supreme moments, for 'when lofty thought Lifts a young heart above its mortal lair, And love and life contend in it for what Shall be its earthly doom, the dead live there, And move like winds of light on dark and stormy air.' 'Of his speculations as to what will befall this inestimable spirit when we appear to die,' Mrs. Shelley has written, 'a mystic ideality tinged these speculations in Shelley's mind; certain stanzas in the poem of _The Sensitive Plant_ express, in some degree, the almost inexpressible idea, not that we die into another state, when this state is no longer, from some reason, unapparent as well as apparent, accordant with our being--but that those who rise above the ordinary nature of man, fade from before our imperfect organs; they remain in their "love, beauty, and delight," in a world congenial to them, and we, clogged by "error, ignorance, and strife," see them not till we are fitted by purification and improvement to their higher state.' Not merely happy souls, but all beautiful places and movements and gestures and events, when we think they have ceased to be, have become portions of the eternal. 'In this life Of error, ignorance, and strife, Where nothing is, but all things seem, And we the shadows of the dream, It is a modest creed, and yet Pleasant, if one considers it, To own that death itself must be, Like all the rest, a mockery. This garden sweet, that lady fair, And all sweet shapes and odours there, In truth have never passed away; 'Tis we, 'tis ours are changed, not they. For love and beauty and delight There is no death, nor change; their might Exceeds our organs, which endure No light, being themselves obscure.'
