sweet or bitter - remain equanimous

Having enjoyed a sweet delicious taste,
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"
