Chapter 24 mentions that people are 'blind despite having eyes.' What does this mean in the context of the chapter's message?

The statement 'blind despite having eyes,' as used in Chapter 24, refers to a state of spiritual ignorance caused by excessive body-consciousness. The chapter explains that because of this focus, people fail to understand their own true welfare. It critiques the pursuit of 'the juice of a momentary pleasure,' emphasizing that the body itself is transient, with no certainty for even a moment. This spiritual blindness prevents individuals from seeing the path towards the supreme goal (Parmartha), which, as the chapter states, is one of the ultimate benefits of devotion to Sai.
