Chapter 10 states that 'All other gods are illusory; the Guru alone is the one eternal God.' How does the text elaborate on the role and significance of the Guru in a devotee's life?

Chapter 10 profoundly emphasizes the supreme importance of the Guru, positioning him as the singular, eternal God beyond the illusory nature of other deities. It explains that to cross the 'ocean of existence' (Bhavasagar), a devotee must place their trust in the Guru, much like one trusts a boatman to cross a worldly ocean. This chapter describes the Guru as being devoted to the welfare of all people and eternally situated in the form of Brahman. Upon seeing a devotee's faith, the Guru places Knowledge (Samvitti) directly in their hand and grants liberation (Moksha) effortlessly, thereby breaking the cycle of birth and death.
