What is the difference between “effective”,” functional” and “functioning” in PAEI terms.

We said that to be effective is the (P)-role. To be effective, you have to serve the clients for whom you exist.

But cancer is effective and not serving anyone but itself. This means it is functioning but is not functional.

Functional means that the (P)-role is done.

What role is functioning, then?

One can be functioning and not functional. Meditation is not serving anyone else but its meditator. It is functioning but not functional.

So, is functioning P-role but then cancer is functioning although it is not functional.

What role is functioning?
