Equanimity
Through the power of observation maintain equanimity
and thus channel the powers of craving and aversion 
toward self transformation.

Observation

Am I easily swayed by my cravings and aversions?

He drinketh the seven seas,

but his heart's thirst is still unquenched,

and he saith,

"Is there yet any more?"

Do my passions make me feel imprisoned or empowered?
Do my aversions cause me to seek out distractions?

A lover is he who is chill in hellfire;

A knower is he who is dry in the sea.
