Chapter 24 mentions that people can be 'blind despite having eyes.' What is the meaning of this statement in the context of the chapter?

In Chapter 24, the statement 'people are blind despite having eyes' refers to a spiritual blindness caused by an over-emphasis on body-consciousness. The text clarifies that because of this strong attachment to the physical body, people fail to understand their own true welfare. They chase the 'juice of a momentary pleasure' in a body that has no certainty from one moment to the next. This spiritual blindness, as described in Chapter 24, prevents them from seeing the path to their own supreme goal and achieving contentment.
