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

In Chapter 24, the phrase 'blind despite having eyes' refers to a spiritual blindness, not a physical one. The text elaborates that this condition is caused by the 'strength of their body-consciousness,' meaning a deep attachment to the physical self and worldly matters. Because of this attachment, people fail to understand their own true welfare. The chapter laments that individuals chase after 'the juice of a momentary pleasure' despite knowing the body is transient and has 'no certainty of it for even a moment.' This preoccupation with fleeting desires, as detailed in Chapter 24, is the blindness that prevents them from seeing the path to their ultimate spiritual goal.
