The beautiful chariots of kings wear out,
This body too undergoes decay.
But the Dhamma of the good does not decay:
So the good proclaim along with the good.

No person can avoid aging and physical death.  No object will last forever.  Even the great pyramid will not last forever.  But the soul, and the good that it does, will last forever.
