Chapter 20 discusses the difficulty of understanding scriptures like the Upanishads. What is the role of a Guru in comprehending such profound knowledge?

Chapter 20 emphasizes that comprehending profound spiritual texts like the Upanishads is nearly impossible without the guidance of a Guru. The text states that the Upanishads contain the essence of the Vedas, but their hidden truths are difficult to grasp without the grace of God and Guru. Chapter 20 warns that a scholar who arrogantly believes they can understand these texts through their own efforts will fail, as the path is difficult at every step without a Guru's grace. In contrast, for a devotee who is humble, detached, and attached to the Guru's feet, the hidden meaning opens up automatically, making the science of Self-knowledge accessible.
