To Whitman, the self is both individual and universal. Man has an individual self, whereas the world, or cosmos, has a universal or cosmic self. The poet wishes to maintain the identity of his individual self, and yet he desires to merge it with the universal self, which involves the identification of the poet's self with mankind and the mystical union of the poet with God, the Absolute Self. Sexual union is a figurative anticipation of spiritual union. Thus the poet's ecstasy is both physical and spiritual, and he develops a sense of loving brotherhood with God and with all mankind. Even the most commonplace objects, such as Leaves, ants, and stones, contain the infinite universe.
