How do the teachings differentiate between a deluded mind and a perfected one who has realized Brahman?

The teachings in Chapter 14 draw a clear distinction based on the perception of duality versus oneness. A deluded mind is one that is stuck in duality due to ignorance and false superimpositions, seeing itself as separate from others and the world. This delusion causes the mind to experience sorrows like birth and death, leaving the creature 'always distressed.' In contrast, a perfected one is someone who has abandoned attributes like name and form to achieve a state of pure knowledge. Such a person, as Chapter 14 explains, is no longer affected by Maya and is 'always engrossed in self-bliss.' They embody the state of oneness, seeing the single, formless Self in all beings.
