Those of old lived on remote mountains and trained in isolated forests; not only was their
involvement with worldly affairs rare, they also severed all their other worldly ties.
You should train yourself in an attitude which conceals Its light and covers Its traces,
for now is the time to train as though your hair were on fire. Were you to waste this time by
surrounding yourself with worldly entanglements, how lamentable that would be!
Alas, the impermanent cannot be relied on, for who knows on what blade of
roadside grass our dew-like life will fall?
