Explain the concept of the Sadguru's transformative touch as detailed in the sixth chapter.

The sixth chapter powerfully illustrates the transformative nature of the Sadguru's touch, using Sai Baba as the prime example. It is described as a wondrous force that brings about profound spiritual change. When Sai Baba places His 'lotus-hand' on a devotee's head, the accumulated impurities from many past lives are washed away, rendering the devotee pure. As Chapter 6 details, this touch is so potent that it can burn away the subtle body, or ego, into ashes—a feat that even the great fire of dissolution cannot accomplish. This act grants stability to a mind prone to idle gossip and fills the devotee's heart with supreme bliss.
