Babylon 5, Season 5: The Wheel of Fire

[Sech Turval comforts Ranger trainee Rastenn, who abandoned his fellow trainee to fight an enemy alone in a moment off uncharacteristic fear.]

Turval:
We create the meaning in our lives. It does not exist independently. Being Anla-shok [Ranger] does not mean worrying about what others will think about us. It does not mean deciding what to do based upon whether or not it serves our sense of ego or destiny. It means living each moment as if it were your last one. It means doing each right thing because it is the right thing. The scale doesn't matter. The where, the when, the how, or in what cause… none of those things matter. In my life, I've discovered very few truths. Here is the greatest truth I know: Your death, Rastenn, will have a meaning if it comes while you're in fullest pursuit of your heart.
