What is the nature of the Sadguru as described in Chapter 18, and what happens when a devotee approaches them?

Chapter 18 describes the Sadguru as the supreme, eternal one, hailed as the "Ruler of Maya," who is beyond duality and without blemish. The text uses a powerful metaphor to explain the devotee's experience: just as a salt doll entering the ocean to bathe cannot return but dissolves, a devotee who approaches the Guru merges with them, losing their individual identity in the divine. As explained in this chapter, when one falls within the Guru's grace, the false logic of "mine" and "thine" disappears, and they are shown the true path.
