According to the provided text from Chapter 6, how does the Sadguru's touch transform a devotee?

Chapter 6 details the wondrous and transformative effects of the Sadguru's touch. It is described as a power that achieves what is seemingly impossible, burning away the subtle body of the ego into ashes with the mere touch of His hand. The chapter further explains that by placing His lotus-hand on a devotee's head, Sai Baba washes away the accumulated impurities of many past births, making the devotee pure. This sacred contact also brings stability to a wandering mind, stopping nonsensical speech, and awakens a state of supreme bliss where tears of joy flow freely, as the eight-fold emotions manifest in the heart.
