How does Chapter 50 describe the transformative effect of the Guru's grace on a disciple's consciousness?

Chapter 50 details a profound inner transformation that occurs through the Guru's grace. It states that when Sai places his hand on a devotee's head, their ego is 'crushed to pieces.' This destruction of the ego initiates a major shift in consciousness, where the internal chant of 'So-ham' (I am He) begins spontaneously. As a result of this realization of unity with the divine, the disciple's perception of the world changes completely, and 'all that is seen is filled with joy.' This passage from Chapter 50 illustrates how the Guru's touch can dissolve individual identity and lead to a state of universal bliss.
