What core message does Chapter 18 convey about the nature of the Sadguru and the devotee's experience?

Chapter 18 begins with powerful salutations to the Sadguru, describing him as the supreme, eternal truth who reveals the illusory nature of the world. It uses a profound analogy to describe the devotee's experience, comparing one who approaches the Guru to a salt doll entering the ocean. As mentioned in the chapter, just as the doll dissolves and becomes one with the water, a devotee merges with the Guru, losing the false sense of individual self. This chapter also emphasizes that by the Guru's grace, the false logic of "mine" and "thine" is eliminated, and He shows the true path to each person according to their worthiness, without creating intellectual conflict.
