That's a couplet from the Selig song "Ohne Dich" (without you).

Es kommt so anders als man denkt
Herz vergeben, Herz verschenkt

Nothing goes as planned, (more or less literally "it happens differently from how you think")
heart given away ("vergeben" means "given away completely", "verschenkt" means "given away as a present")
