Love, Hope, and Self-esteem, like clouds depart And come, for some uncertain moments lent. Man were immortal, and omnipotent, Didst thou, unknown and awful as thou art, Keep with thy glorious train firm state within his heart. Thou messgenger of sympathies, That wax and wane in lovers' eyes -- Thou -- that to human thought art nourishment, Like darkness to a dying flame! Depart not as thy shadow came, Depart not -- lest the grave should be, Like life and fear, a dark reality. Percy Bysshe Shelley
