How important is a Guru in the process of realizing the Soul's true nature as a non-doer?

The role of a Guru is presented as absolutely essential. Chapter 8 teaches that Guru and Brahman are not two separate entities, and gaining this non-dual knowledge makes it easy to cross the illusions of Maya. The text emphasizes that the liberation of the human body is not known to anyone without a Guru, stating, 'Only when the Guru holds the hand do the dull souls get redeemed.' Furthermore, the success of one's spiritual path is directly proportional to one's faith in the Guru. As Chapter 8 explains, the conduct of holy men is a powerful instruction, often more effective than scriptures, as their actions and even silence can free souls from bondage.
