What does michelangelo mean when he describe life like a block of marble with the soul trapped inside?

When Michelangelo described life as a block of marble with the soul trapped inside, he was likely referring to the idea that each person's true essence, or soul, is hidden within them and needs to be revealed or "unearthed" through self-discovery and personal growth. Just as a sculptor must chip away at a block of marble to reveal the hidden masterpiece within, individuals must work on themselves to uncover their true potential and purpose in life. This metaphor suggests that life is a process of self-realization and actualization, where one must constantly strive to uncover and express their innermost self.
