“Beware of your own self as your bitterest enemy, and do not follow your own will, mind, taste or feeling, if you do not wish to get lost.
Therefore always be fully armed against yourself, and when your desire inclines towards something, however holy, strip it naked of everything extraneous and place it, alone, before your God, with the greatest humility, imploring Him that in this His will and not your own may be done.
Do this with a sincere and heart-felt surrender to the will of God, with no trace of self-love, knowing that you have nothing in yourself and can do nothing by yourself in your work of salvation.”
St. Nicodemos of the Holy Mountain; Unseen Warfare Chpt 17
