be glad!

you shall above all things be glad and young
   for if you're young,whatever life you wear

   it will become you;and if you are glad
   whatever's living will yourself become.
   girlboys may nothing more than boygirls need:
   i can entirely her only love

   whose any mystery makes every man's
   flesh put space on;and his mind take off time

   that you should ever think,may god forbid
   and (in his mercy) your true lover spare:
   for that way knowledge lies,the foetal grave
   called progress,and negation's dead undoom.

   i'd rather learn from one bird how to sing
   than teach ten thousand stars how not to dance
