Are you sure you’re going to live for ten more years? Forget it! You can’t even guarantee that you will live for another five minutes.
If you could be assured that you will have the leisure to complete all your work, and still have enough time left for the dharma, then it would be all right to wait a few years to practice; but if you wait you are just fooling yourself.
Look at how many corpses are carried to the cemetery every day in just one large city. Still you ignore death. Don’t be blind. Ponder again and again the suddenness with which death may strike.
