Each of us is born with a box of matches inside us

"Each of us is born with a box of matches inside us but we can't strike them all by ourselves; we need oxygen and a candle to help. In this case, the oxygen for example, would come from the breath of the person you love; the candle would be any kind of food, music, caress, word, or sound that engenders the explosion that lights one of the matches. For a moment we are dazzled by an intense emotion. A pleasant warmth grows within us, fading slowly as time goes by, until a new explosion comes along to revive it. Each person has to discover what will set off those explosions in order to live, since the combustion that occurs when one of them is ignited is what nourishes the soul. That fire, in short, is its food. If one doesn't find out in time what will set off these explosions, the box of matches dampens, and not a single match will ever be lighted. — From the novel, Like Water for Chocolate, by Laura Esquivel
