What is the specific significance of the Sadguru's touch as explained in Chapter 6?

Chapter 6 elaborates on the wondrous and transformative power of the Sadguru's touch. It is described as a touch that can burn away the subtle body, or ego, which even the fire of dissolution cannot destroy. When the Sadguru places His lotus-hand on a devotee's head, it is said to wash away the impurities accumulated over many births. This chapter also mentions that if one's mind is wandering into idle gossip, the Guru's touch can grant stability to that nonsensical speech. Ultimately, this touch is a profound blessing that purifies the devotee and fills their heart with self-bliss.
