The Lovers are one of the most complex cards in the Major Arcana, standing for the
love in common and the alchemy of the universe. The trump represents
the power of life, the creative love, which can be quite impressive, but also destructive
when one happens to disregard the fire of instinct, burning down rationalism.
The card also represents a decision, the farewell to a former way of life and the full acceptance of love uncompromising. It doesn't necessarily mean that the 'love' is a person that you tie your knots to with fancy tungsten wedding bands - it can be a passion, a desire, or even a profession, like going to sea or working with horses. Many people who lead an adapted, settled life actually have deep desires and hidden wishes, that they don't dare show, that they constantly fight back, surpressing their own happiness.
The Lovers can mean that someone should be honest, make a clear decision for this love, the fulfilling of a wish, of a desire, and stand by it.
Apart from this, the Lovers can say that a peaceful combination of existing contrasts or contradictions is a better solution than any confrontation - diplomacy instead of war.
