William Shakespeare - Hamlet

Angels and ministers of grace defend us!- Be thou a spirit of health or goblin damn'd, Bring with thee airs from heaven or blasts from hell, Be thy intents wicked or charitable, Thou com'st in such a questionable shape That I will speak to thee: I'll call thee Hamlet, King, father, royal Dane; O, answer me! Let me not burst in ignorance; but tell Why thy canoniz'd bones, hearsed in death, Have burst their cerements; why the sepulchre, Wherein we saw thee quietly in-urn'd, Hath op'd his ponderous and marble jaws To cast thee up again! What may this mean, That thou, dead corse, again in complete steel, Revisit'st thus the glimpses of the moon, Making night hideous, and we fools of nature So horridly to shake our disposition With thoughts beyond the reaches of our souls? Say, why is this? wherefore? what should we do?
