Quote by St. Maximus the Confessor ~ self love (gluttony, avarice, vain-glory)

   Flee from self-love, the mother of malice, which is an irrational love for the body. For from it are born the three chief sinful passions: gluttony, avarice, and vainglory, which take their causes from bodily needs, and from them all the tribe of the passions is born. This why we must always oppose self-love and fight against it. Whoever rejects self-love will easily conquer all the other passions with the help of God: anger, despondency, rancor, and the others. But whoever is retained by self-love will even unwillingly be conquered by the above-named passions.


(St. Maximus the Confessor, Chapters on Love, 2.59,8)
