Based on Chapter 19, can you outline the hierarchy of existence from the Soul to the ultimate goal, the Pure Brahman?

Chapter 19 presents a spiritual hierarchy based on subtlety. It begins with the Soul, which is described as a Great Power. Even subtler than the Soul is the Unmanifest, also known as Avyakta, Space, or Maya. Going deeper, the text reveals that subtler than all of these is the Purusha, or the Supreme Being. This Purusha is identified as the ultimate goal and is equated with the Pure Brahman. It is in this state, as Chapter 19 explains, that the senses and the mind finally find their rest, achieving the ultimate state of being.
