As stated in the sutras, "Existence in the human realm is rare, and all is impermanent. " Most of you here are already in your 30s and 40s. The remaining days, a few more decades at the most, are really not that long and will soon pass by before you know it. Unfortunately, there is no guarantee the opportunity to practice will present itself again in the next life you fail to seize it this time. So the point is to lay the necessary foundation now as the stepping-stones leading to a better start for the next life.
