Based on Chapter 10, what is the significance of the Guru in a devotee's life, and how is this path presented as superior to other spiritual practices?

Chapter 10 establishes the supreme significance of the Guru, presenting Him as the one eternal God while all other gods are described as illusory. The text emphasizes that placing faith in the Sadguru's feet is the most effective spiritual path, as it can change one's destiny. Chapter 10 further explains that where the service of the Sadguru is pure, the worldly existence (Samsara) is completely destroyed. This path is presented as superior because it eliminates the need for the "struggle of logic, Mimamsa, or other intellectual acrobatics." The Guru acts as a boatman across the ocean of existence, effortlessly granting liberation and bliss to those with devotion and faith.
