In readings, Card 6 often refers to a relationship that is based on deep love - the strongest force of all. The relationship may not be sexual, although it often is or could be. More generally, the Lovers can represent the attractive force that draws any two entities together in a relationship - whether people, ideas, events, movements or groups.
Card 6 can also stand for tough value choices and the questioning that goes with them. In some decks, the Lovers shows a man torn between two women - a virgin and a temptress. This rather old-fashioned triangle symbolizes the larger dilemmas we face when we are tempted between right and wrong.
The Lovers can indicate a moral or ethical crossroads - a decision point where you must choose between the high road or the low road. This card can also represent your personal beliefs because to make such a decision you must know where you stand. Following your own path can mean going against those who are urging you in a direction that is wrong for you.
