Chapter 24 mentions that people can be 'blind despite having eyes.' What does this 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 explains that people afflicted with this 'blindness' are unable to understand their own true welfare. They become preoccupied with chasing momentary pleasures, spreading their 'lap' for fleeting satisfaction, even though the body itself is transient and uncertain. This spiritual blindness prevents them from seeing the path to achieving the supreme goal, or Parmartha. Essentially, as this chapter points out, their focus on the physical and temporary world blinds them to deeper spiritual truths and their own ultimate well-being.
