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

The phrase 'blind despite having eyes' in Chapter 24 refers to a state of spiritual ignorance caused by excessive body-consciousness. The text clarifies that this is not a physical blindness but a failure to understand one's own true welfare. According to Chapter 24, this spiritual blindness leads people to chase the 'juice of a momentary pleasure,' causing them to spread their 'lap' for fleeting desires while ignoring the transient and uncertain nature of the physical body. They are unable to see the path to their own ultimate well-being and the supreme goal, or Parmartha.
