What are the specific effects of Sai Baba's 'blessing hand' as detailed in Chapter 6?

According to Chapter 6 of the Sai Satcharitra, the touch of Sai Baba's hand has multiple powerful effects on a devotee. When His blessing hand, along with Udi from the Dhuni, is placed on someone's head, it causes the heart to overflow with 'self-bliss' and love to pour from the eyes. The text emphasizes that this touch washes away the 'accumulated impurities of many births,' making the devotees pure. Furthermore, it is said to grant stability to wandering thoughts and nonsensical speech. Most profoundly, the chapter claims the touch of the Guru's hand has the unique power to burn away the subtle body of ego, which is something that even the 'fire of dissolution' cannot achieve.
