In Chapter 24, the author mentions that people are 'blind despite having eyes.' What does this metaphor mean in the context of the chapter?

Chapter 24 uses the metaphor 'blind despite having eyes' to describe people who are so absorbed in their body-consciousness that they fail to understand their own true welfare. The chapter elaborates that this blindness prevents them from seeing the transient nature of the physical body, which is uncertain even for a moment. Instead of seeking lasting truth, they are caught up in chasing momentary pleasures. This metaphor highlights a central theme in the chapter: the need to look beyond the physical and worldly to grasp the spiritual essence that Sai Baba taught.
