According to Chapter 27, what are the signs that a devotee is truly absorbed in the Guru's story, and what is the source of this experience?

Chapter 27 describes the profound experience of a devotee listening to the Guru's pure story. The signs include physical and emotional reactions such as perspiration breaking out over the body, eyes filling with tears of love, a moved heart, and goosebumps rising repeatedly. This absorption can even lead to weeping and sobbing. The chapter explains that this experience, which destroys conflicts and distinctions, is the awakening of the Guru's grace. This grace is beyond the reach of the senses and can only be found through a Sadguru, requiring ultimate faith in the Guru's feet.
