The final verses of Chapter 21 have sometimes been taken to be the final teaching of the Sutra and therefore to be especially important. They express, quite simply, the power and possibility that each of us has to make a positive difference wherever we are.

After the extinction of the Tathagata,
Anyone who knows the sutras preached by the Buddha,
Their causes and conditions and proper order,
Will teach them truthfully in accord with their true meaning.
Just as the light of the sun and the moon Can dispel darkness,
Such a person, working in the world,
Can dispel the gloom of living beings, Leading innumerable bodhisattvas
Finally to dwell in the One Vehicle.
