The Lovers is associated with the star sign Gemini, and indeed is also known as The Twins in some decks. (I consider myself a Gemini, FYI.)
The Lovers represent the impulse that drives us out of the garden, towards adulthood. Sometimes, that impulse manifests as curiosity (Eve, Pandora, Psyche); sometimes it manifests as sexual desire (most horror and teen movies); sometimes it manifests as duty (a soldier heeding the call). Could even manifest as the intense desire to go on an adventure botany quest. The quest for the Other. Whatever it is, once we have stepped passed the threshold, there is no returning to the garden.
In some traditions, The Lovers represents relationships and choices. Its appearance in a spread indicates some decision about an existing relationship, a temptation of the heart, or a choice of potential partners. Often an aspect of the Querant's life will have to be sacrificed; a bachelor(ette)'s lifestyle may be sacrificed and a relationship gained (or vice versa), or one potential partner may be chosen while another is turned down. Whatever the choice, it should not be made lightly, as the ramifications will be lasting.
Now, good Indian food and a silly movie about Nascar drivers, I think.
