According to Chapter 6, what happens when a Sadguru like Sai Baba places his hand on a devotee's head?

Chapter 6 of the Sai Satcharitra beautifully describes the profound effects of the Sadguru's touch. When Sai Baba places His blessing hand, often with Udi, on a devotee's head, their heart overflows with self-bliss and love pours from their eyes. This wondrous touch is so powerful that it can burn away the subtle body, or ego, into ashes. Furthermore, the text explains that this act washes away the accumulated impurities of many past births, purifying Sai's loving devotees and bringing them immense spiritual benefit.
