Chapter 24 mentions that people can be 'blind despite having eyes.' What is the cause of this spiritual blindness according to the text?

In Chapter 24, the concept of being 'blind despite having eyes' is attributed to a strong attachment to body-consciousness. The text explains that it is this very attachment that prevents people from understanding their own true welfare. This spiritual blindness causes individuals to chase momentary pleasures, spreading their 'lap' for the juice of a fleeting experience. As Chapter 24 points out, this happens despite the fact that the physical body is completely transient, with 'no certainty of it for even a moment.' Therefore, the root cause of this blindness is the failure to see beyond the physical form and its temporary desires.
