Majivuno ni tabia ya mtu kujipongeza mno kutokana na sifa alizonazo. Yanatokana na kiburi na kufikia hatua ya majigambo ya uongo ambayo ni chukizo kwa wengine. Katika dini mbalimbali yanatazamwa kama aina ya kujiabudu badala ya Mungu. Katika maadili ya Ukristo (Lk 14:11; 1Pet 5:5), majivuno ni mmojawapo kati ya mizizi ya dhambi (au vilema vikuu au vichwa vya dhambi) inayozaa dhambi nyingine nyingi (1Kor 5:6-7). Jina la Kilatini (vanitas au vanagloria, kwa Kiingereza: vanity au vainglory) linahusisha tabia hiyo na ubatili. Kiburi Kujiamini During the Renaissance, vanity was invariably represented as a naked woman, sometimes seated or reclining on a couch. She attends to her hair with comb and mirror. The mirror is sometimes held by a demon or a putto. Symbols of vanity include jewels, gold coins, a purse, and the figure of death.
