Chapter 24 states that people are 'blind despite having eyes.' What is the philosophical meaning of this blindness as explained in the text?

In Chapter 24, the statement that people are 'blind despite having eyes' refers to a spiritual or intellectual blindness, not a physical one. The text clarifies that this condition is caused by the 'strength of their body-consciousness,' which prevents them from understanding their own true welfare. This attachment to the physical self is further criticized by noting the transient nature of the body, of which there is 'no certainty of it for even a moment.' Despite this, people focus on tasting the 'juice of a momentary pleasure,' effectively being blind to the supreme spiritual goal, or Parmartha, mentioned within the chapter.
