"Shape of My Heart" is a song by Sting which has been covered by Josh Groban. The song talks about a man who plays cards not for the purpose of winning or respect, but to find answers, to discover the sacred geometry of chance, and to understand the hidden law of probable outcomes. The lyrics also delve into the idea that the way a person plays cards can reveal something about their nature, as certain cards hold specific meanings and are connected with certain traits. For example, the spades are connected with soldiers and the clubs are weapons of war. Diamonds are seen as symbols of wealth and material success. The chorus of the song repeats the refrain, "But that's not the shape of my heart", suggesting that the true nature of the man playing the cards is not revealed by the cards he holds, but by deeper aspects of his personality that cannot be determined through gambling and games. Ultimately, the song speaks to larger themes of identity, perception, and the search for greater meaning. The lines "But those who speak know nothing / And find out to their cost" suggest that the man playing the cards may know more than those who are quick to judge him based on his actions. The song's overarching message is one of challenging assumptions and moving beyond surface-level appearances to discover deeper truths about oneself and others.
