In the context of monism, what does "the wax seal" analogy represent?

The wax seal analogy, often attributed to the philosopher Spinoza, illustrates the idea of the unity of body and mind by demonstrating how different attributes of a single substance can express themselves. In this analogy, the wax seal represents how the physical properties of wax (its shape and imprint) and its underlying substance cannot be separated in a meaningful way. Just as the seal and the wax are two expressions of the same material, the body and mind, in a monistic view, are two aspects of a single substance. This analogy emphasizes that physical and mental states are interdependent rather than divided, aligning with monistic philosophy, which asserts that all things (including mind and body) are fundamentally unified.
