Sorrow is an inevitable part of love, much like how gravity naturally exists because of mass. This suggests that experiencing pain or sadness is a natural consequence of deep emotional connections. Love and sorrow are intertwined, with one often leading to the other, highlighting the complexity of human relationships.

According to Lawrence Durrell in his book Sir, "Sorrow is implicit in love as gravitation is implicit in mass," emphasizing that emotional pain is an inherent aspect of love, just as gravity is an inherent property of matter. This perspective acknowledges that love's profound beauty is often accompanied by inevitable suffering, making both experience inseparable.
