It means:
Going when you would rather stay and
staying when you would rather go.
Remaining silent when you would rather speak and
speaking when you would rather remain silent.
Giving away that which you would rather keep.
Walking away from loved ones.
Loving your enemies.
Walking away from a meal you just finished preparing.
Leaving behind worldly security and
trusting in that which you can not see.
Changing the way you look.
Changing the way you speak.
Changing the way you think.
Changing the way you eat.
Being set apart.
Counting time as not your own.
Heartbreak.
Being mocked and scorned.
Doing things that seem senseless.
Exchanging earthly pleasures for heavenly treasures.
Freedom from worry.
Freedom from fear.
Singing in the shower.
Blissful sleep.
Adventures galore.
Having your best friend continually with you.
Being loved like you have never been loved before.
Perfect peace.
