According to Chapter 27, what are the signs of a true devotee's experience when listening to Sai's stories, and what is the source of this experience?

Chapter 27 provides a vivid description of the ideal devotee's experience while absorbed in Sai Baba's pure story. The signs include physical reactions like perspiration breaking out all over the body, goosebumps rising repeatedly, and the eyes filling with tears of love. Emotionally, the heart is moved, leading to weeping and sobbing. This profound state, as explained in Chapter 27, is the 'awakening of the Guru's grace.' It is an experience beyond the reach of the senses that can only be found through the Sadguru, leading to the destruction of internal conflicts and the subsiding of the six passions like lust.
