心 (xīn): Heart, mind, or core. In this context, it refers to the deepest, most genuine desires held within a person's heart.
想 (xiǎng): To think, to wish, to desire, or to hope for. This is the action of forming an intention or aspiration.
事 (shì): Matter, affair, event, or thing. This represents the substance of the wish—the goal, the project, or the life event itself.
成 (chéng): To succeed, to accomplish, to become, or to be completed. This is the positive outcome, the successful realization of the wish.
These characters combine literally and poetically: “Heart (心) thinks/wishes (想), the matter (事) is accomplished (成).” The structure implies a direct and powerful link between one's intentions and the results, making it a very encouraging and hopeful phrase.
