According to the text, what is the transformative effect of the Guru's touch on a disciple's ego and perception?

Chapter 50 describes a profound spiritual event that occurs through the Guru's grace. It is mentioned that when Sai Baba's hand is placed upon a devotee's head, their ego is completely 'crushed to pieces.' This destruction of the ego is not a negative event but a liberating one that initiates a deep internal shift. Following this, the inner chant of 'So-ham' (I am He) begins spontaneously within the disciple. As Chapter 50 explains, this leads to a new state of consciousness where 'all that is seen is filled with joy,' signifying a perception of divinity in everything.
