Chapter 24 contains the phrase that people are 'blind despite having eyes.' What is the deeper, philosophical meaning of this statement as explained in the chapter?

The statement in Chapter 24 that people are 'blind despite having eyes' refers to a state of spiritual ignorance, not physical blindness. The chapter clarifies that this blindness is caused by the 'strength of their body-consciousness,' which prevents them from understanding their own true welfare. People become so engrossed in the transient nature of the physical body and the pursuit of 'momentary pleasure' that they lose sight of the supreme goal (Parmartha). This commentary serves as a profound teaching on the dangers of materialism and attachment to the ephemeral world.
