My son, I ask you to be watchful and to be on your guard, acquainted with those who lie in ambush against you.
The spirit of cowardice and the spirit of distrust walk hand in hand; the spirit of lying and the spirit of deceit walk hand in hand;
the spirits of greed and trafficking, of perjury and dishonesty, and that of jealousy walk hand in hand;
the spirit of vanity and the spirit of gluttony walk hand in hand;
the spirit of fornication and the spirit of impurity walk hand in hand;
the spirit of enmity and the spirit of sadnesss walk hand in hand.
Woe to the wretched soul in which they make their home and of which they make themselves masters. They hold such a soul far from God, because it is in their power. It sways from side to side till it ends in the abyss of hell.
[St. Pachomius the Great, Instruction Concerning a Spiteful Monk (Pach. Instr. 1), 10]
