What overarching message about the importance of a Guru is conveyed at the start of Chapter 10?

The beginning of Chapter 10 conveys a powerful message about the supreme importance of the Guru. It states that while other gods are illusory, 'the Guru alone is the one eternal God.' This chapter emphasizes that simply remembering the Guru with love can untie the knot of birth and death, which is described as the best spiritual practice (Sadhana). It asserts that placing faith in the Guru's feet can change one's destiny and that the Guru acts as a boatman, helping devotees cross the ocean of worldly existence and overcome all miseries, ultimately leading them to liberation.
