What are the emotional and spiritual transformations a devotee undergoes through the grace of the Sadguru, as described in Chapter 6?

Chapter 6 poetically describes the profound transformations experienced by a devotee. When the Sadguru's blessing hand, along with Udi, falls upon the head, the heart overflows with self-bliss and love pours from the eyes. Looking at Sai's beautiful form can cause the throat to choke with supreme bliss and tears of joy to flow. The text mentions that the eight-fold emotions manifest in the heart. Spiritually, the Sadguru's touch washes away impurities from many births, awakens the sense of 'I am He' (Soham), and dissolves the sense of 'me and mine', ultimately revealing the harmony of non-duality (Advaita).
