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; while truth the while
Doth falsely blind the eyesight of his look:
Light seeking light doth light of light beguile:
So, ere you find where light in darkness lies,
Your light grows dark by losing of your eyes.
