068 Arhat Upāli (Understanding Emptiness and Concentration)
The vicissitudes of the world and the ups and downs of fate are beyond one's control. Time flies easily; if you do not work diligently now, you will surely accomplish nothing in old age.
For those who receive this verse, one's destiny is volatile, and much time has been wasted. If one still does not calm down and work diligently now, one will accomplish nothing in life.
