Can you describe the hierarchy of existence from the soul to the Supreme Being as outlined in Chapter 19?

Chapter 19 presents a subtle hierarchy of existence, starting with the Soul (Atma), which it calls the Great Power. It then explains that subtler than the soul is the Unmanifest (Avyakta), which is described as Space or the Unmanifest Nature, also known as Maya. Going even further, the chapter states that subtler than all of these is the Purusha, or the Supreme Being. This Purusha is identified as the ultimate goal where the senses and mind finally find rest. This ultimate state is what the text refers to as the Pure Brahman, the final destination beyond the soul and the illusions of Maya.
