Based on Chapter 49, what is the supreme importance of the Sadguru and how should a devotee relate to them?

Chapter 49 of the Sai Satcharitra places the Sadguru in the highest esteem, noting that even the Vedas and Puranas grew weary trying to praise Him. Sai is described as the resting place for His devotees and the remover of worldly troubles. The text clearly states that the greatest spiritual practice, surpassing pilgrimages, sacrifices, and even singing Hari's name, is the meditation on one's own Guru. For a devotee, as mentioned in Chapter 49, love for the Guru's feet is the only true wealth, and Sai alone should be the object of their meditation and worship.
