The text states that people are 'blind despite having eyes' due to body-consciousness. How does this spiritual blindness prevent the attainment of contentment and supreme bliss?

According to the philosophy presented in Chapter 24, 'body-consciousness' is a state of spiritual blindness that keeps a person from understanding their own true welfare. This attachment to the physical form and its fleeting sensations causes one to chase momentary pleasures, mistaking them for real happiness. This state directly obstructs the path to contentment, which Chapter 24 states is achieved through "Meditation on one's true self." By being fixated on the body, one cannot perform this inward meditation. Consequently, they remain trapped in the delusion of worldly fears and are unable to attain the internal peace ('Nij-vishranti') and supreme bliss promised to those who transcend this limited perspective.
