In his metaphysics, everything that exists is part of a single substance, which he calls Deus sive Natura (God or Nature). This substance is infinite, eternal, and indivisible, encompassing both mind and body as two aspects of the same fundamental reality. As such, the distinction between subject and object, or mind and matter, is ultimately illusory; they are simply different attributes of the same underlying substance.
