Chapter 24 states that people can be 'blind despite having eyes.' How does this chapter explain this blindness and what causes it?

In Chapter 24, the author makes the observation that many people are 'blind despite having eyes,' meaning they are spiritually unaware. This blindness is not physical but is caused by the strength of their body-consciousness. Because they are so identified with their physical form and its transient nature, they fail to understand their own true, lasting welfare. The chapter elaborates that despite knowing the body's uncertainty from one moment to the next, people still spread their 'lap' of desires, seeking to taste the juice of momentary, fleeting pleasures. This preoccupation with the temporary world is the source of their spiritual blindness.
