According to Chapter 27, what are the signs that a devotee is truly experiencing the Guru's grace while listening to Sai's stories?

Chapter 27 provides a vivid description of the physical and emotional manifestations of a devotee experiencing the Guru's grace. While listening to Sai's pure story-nectar, a devotee may experience perspiration breaking out over their body, their eyes filling with tears of love, and goosebumps rising repeatedly. The chapter also mentions that the heart becomes moved, and even weeping and sobbing may occur. These reactions, along with the subsiding of the six passions and the emergence of supreme love, are considered signs of the awakening of the Guru's grace, which can only be found through ultimate faith in the Sadguru's feet.
