Today I have brought nothing of material substance to offer you, only the Dhamma, the teachings of the Lord Buddha. You should understand that even the Buddha himself, with his great store of accumulated virtue, could not avoid physical death. When he reached old age he ceded his body and let go of the heavy burden. Now you too must learn to be satisfied with the many years you've already depended on the body. You should feel that it's enough.
Like household utensils that you've had for a long time - cups, saucers, plates and so on - when you first had them they were clean and shining, but now after using them for so long, they're starting to wear out. Some are already broken, some have disappeared, and those that are left are wearing out, they have no stable form. And it's their nature to be that way.
Your body is the same... it's been continually changing from the day you were born, through childhood and youth, until now it's reached old age. You must accept this. The Buddha said that conditions, whether internal, bodily conditions or external conditions, are not self, their nature is to change. Contemplate this truth clearly.
