Chapter 24 mentions people being 'blind despite having eyes.' What does this metaphor mean in the context of the chapter's teachings?

In Chapter 24, the phrase 'blind despite having eyes' is a metaphor for spiritual ignorance caused by excessive body-consciousness. The text clarifies that these people are not physically blind but are unable to perceive their own true welfare. They are preoccupied with chasing momentary pleasures, even though the physical body's existence is not guaranteed for even a moment. According to the teachings in Chapter 24, this spiritual blindness prevents them from understanding the path towards the supreme goal (Parmartha) and realizing the contentment that comes from meditating on one's true self.
