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.
Why, all delights are vain, but that most vain Which, with pain purchased, doth inherit pain: As, painfully to pore upon a book, To seek the light of truth, which truth the while Doth falsely blind the eyesight of his look.
