How does the author describe the nature of the Sadguru, and why is this salutation saved for last?

The author describes the Sadguru as the ultimate reality and the source of all inspiration. According to Chapter 1, the Sadguru is the "resting place of all moving and unmoving beings," the "foundation of the entire universe," and a being of pure compassion. His dwelling is beyond 'Maya' or the 'Unmanifest,' a realm that even the Vedas and scriptures fall silent in describing. The author saves this salutation for last, comparing it to a "sweet morsel" kept for the end of a meal. This deliberate placement emphasizes the supreme importance of the Guru, suggesting that all other respects and salutations culminate in the ultimate surrender to the Sadguru, who is the giver of the intellectual inspiration needed to write the book.
