Heart, Heart, if you're beset by invincible
griefs, rise!, withstand contrary-wise
offering up your chest, and against the tricks
of the enemy steel yourself firmly. And should you come out
victorious, dissemble, heart, don't boast,
nor, defeated, should you debase yourself crying
at home. Don't let them matter too much
your joy in success, your sorrow in failure.
Understand that in life alternation rules.
