Hermeticism is a philosophy that focuses on spiritual practices and beliefs. It's based on the writings of a person called Hermes, who some people think was an ancient Egyptian philosopher. Hermeticism teaches that the universe is made up of one divine, spiritual power that we can access with our minds through spiritual practice. Hermeticism suggests that we can use this power to better our lives and become closer to the divine. Hermeticism also suggests that thoughts create reality, and that we should strive to make our thoughts positive in order to create a better life for ourselves.
