According to Chapter 27, what are the physical and emotional signs that indicate the awakening of a Guru's grace in a devotee?

Chapter 27 describes several profound physical and emotional responses that signify the awakening of a Guru's grace, especially while listening to the Guru's stories. These signs include perspiration breaking out over the body, eyes filling with tears of love, and the life-force being captivated. The text also mentions the heart being moved, goosebumps rising repeatedly, and even frequent weeping and sobbing among listeners. As cited in Chapter 27, these experiences are accompanied by the destruction of mutual conflicts and the vanishing of distinctions between small and great, which are all part of this internal spiritual awakening.
