Nikos Kazantzakis

The struggle between God and man breaks out in everyone, together with the longing for reconciliation... God does not love weak souls and flabby flesh. The spirit desires to wrestle with flesh which is strong and full of resistance. It is a carnivorous bird which is incessantly hungry; it eats flesh and, by assimilating it, makes it disappear.

Sometimes the routes leading to feelings of anger are so convoluted and circuitous that it takes enormous skill to discern their original source, or fountainhead. But regardless of the reason for or the source of the anger or the relative ease or complexity in perceiving either the anger or its source - everybody, but everybody, gets angry.
