Based on Chapter 50, what is the effect of Sai Baba's grace on a devotee, and how is his essential nature described?

Chapter 50 describes Sai Baba as the formless taking form, stating, "Sai is purely an embodiment of consciousness; the Unmanifest itself has taken form." He is portrayed as desireless yet deeply compassionate towards his faithful devotees. The transformative power of his grace is vividly illustrated. The text explains that when Sai Baba places his hand on a devotee's head, their ego is "crushed to pieces." This act of grace initiates an inner spiritual awakening, where the chant of "So-ham" (I am He) begins spontaneously, and the devotee's perception shifts to see joy in everything. This description emphasizes that Sai's grace directly dismantles the ego and reveals the divine consciousness within.
