And having sometimes tasted what is bitter,
Do not greedily enjoy the sweet taste,
Do not feel aversion toward the bitter.
"When touched by pleasant contact, do not be enthralled,
Do not tremble when touched by pain.
Look evenly on both the pleasant and painful,
Not drawn or repelled by anything."
~ Buddha, "The Connected Discourses of the Buddha"
"Just as a solid rock
is not shaken by the storm,
even so the wise
are not affected by praise or blame."
~ Dhammapada 81
