The text mentions being hidden behind a 'screen of nescience'. What does this mean and how does Chapter 26 suggest one can overcome it?

The 'screen of nescience' mentioned in Chapter 26 refers to the veil of ignorance that obscures one's true, eternal nature. Due to this ignorance, a person's intellect is mounted on 'false logic,' causing them to perceive the illusory world as real, much like mistaking a rope for a snake in the dark. To overcome this, the chapter emphasizes the critical role of the Guru. The path to dissolving this nescience involves placing unshakeable faith in the words of the Guru and the Vedanta scriptures. Through the Guru's grace, the light of non-dual bliss shines forth, the illusion dissolves, and the mystery of the Self is solved through direct, personal experience rather than mere intellectual effort.
