Meaning of "Heart of Mine" by Bob Dylan

In "Heart of Mine," Bob Dylan personifies the heart as a separate entity that needs to be controlled and kept in check. The narrator advises his heart to not reveal its emotions, to not show vulnerability, and to not get too attached to someone who may not reciprocate those feelings. The heart is described as cunning and potentially dangerous, warning that falling in love could lead to pain and trouble. The repeated phrases of "Don't let her know," "Don't let her see," and "Don't let her hear" emphasize the importance of maintaining emotional control and not letting feelings of love override reason. This song serves as a reminder to be cautious with matters of the heart, to protect oneself from potential heartbreak, and to not act impulsively when it comes to emotions.
