According to the beginning of Chapter 6, what are the spiritual effects of the Sadguru's touch on a devotee?

The initial verses of Chapter 6 detail the profound spiritual effects of the Sadguru's touch. When Sai Baba places His lotus-hand on a devotee's head, it is said to burn away the subtle body, or ego, into ashes—something even the fire of dissolution cannot do. This divine touch washes away the impurities of many past births, purifying the devotee. As described in Chapter 6, this experience causes the heart to overflow with self-bliss and love, often leading to tears of joy and the manifestation of the eight-fold emotions in the heart.
