Here are some of my favourites I can think of right now.
Mindfulness is the way to the Immortal, unmindfulness the way to
death. Those who are mindful do not die, (whereas) the unmindful
are like the dead.
Mindful among the unmindful, wide awake among the sleeping, the man
of good understanding forges ahead like a swift horse outdistancing
a feeble hack.
~ Appamadavagga - Mindfulness (verses 21-32)
