What are the details of the Udi distribution ceremony after the noon Aarti as described in Chapter 20?

Chapter 20 provides a beautiful and detailed account of Sai Baba distributing Udi. After the midday Aarti, Baba would stand at the edge of the Masjid with a "most merciful gaze." Devotees would eagerly rush to embrace his feet. Baba would then fill his handfuls with Udi and place the sacred ash into the cupped hands of the devotees. In a gesture of immense affection and blessing, he would also use his thumb to apply the Udi directly to their foreheads. The chapter emphasizes that this act was filled with "boundless love in his heart," showing it was a profound expression of his grace rather than a mere ritual.
