The final link is represented by a dying person. Ageing is both progressive, occurring every moment of our lifetime, and degenerative which leads to death.

In future one is assured, given enough of Unknowing and Craving, of lives without end but also of deaths with end. The one appeals to greed but the other arouses aversion. One without the other is impossible. But this is the path of heedlessness. The Dhamma-path leads directly to Deathlessness, the going beyond birth and death, beyond all dukkha.

We are well exhorted by the words of Acharya Nagarjuna:

"Do you therefore exert yourself:
At all times try to penetrate Into the heart of these Four Truths;
For even those who dwell at home,
they will, by understanding them ford the river of (mental) floods."

L.K. 115

This is a very brief outline of the workings of this wheel which we cling to for our own harm and the hurt of others. We are the makers of this wheel and the turners of this wheel, but if we wish it and work for it, we are the ones who can stop this wheel.
