We come to the conclusion of Conference 20 on repentance and reparation and consider the depth of the desert Fathers understanding of the human person.  Abba Pinufius sets off carnal sins from the others as those that one would not want to recall as a means of uprooting the disposition to them.  Such sins, touching upon our natural appetites and desires carry within them the danger of drawing us back into them if we allow them to return to memory and imagination.  Pinufius is not treating such natural appetites as evils but rather respecting their power and importance to our identity as human beings.  For such reasons they are not to be treated casually or lightly in the spiritual battle. We must instead turn our minds to heavenly things - the desire for God and the virtues.
