Hinduism has a beautiful myth about the origins of love. In the beginning, there was a superbeing called Purusha. This being was without desire, craving, fear, or indeed the impulse to do anything at all—since the universe was already perfect and complete.
Then the creator Brahma took out his divine sword and split Purusha in two. Sky became separate from earth, darkness from light, life from death, male from female. Each of these set off passionately to reunite with its severed half.
As humans, we too are seeking unity, and love is the word we use for that search.
