Can you describe the daily rituals associated with the Dhuni and Udi as presented in Chapter 33 of Sai Satcharitra?

As presented in Chapter 33, Sai Baba's daily rituals involving the Dhuni and Udi were central to his interactions with devotees. The source of the Udi was the Dhuni, a sacred fire that Baba kept constantly burning by feeding it with dry logs of firewood he would purchase. The ash from this fire became the sacred Udi. The chapter emphasizes that distributing this Udi was a consistent, daily practice. Baba would give it to devotees in the mornings, afternoons, and evenings, never sending anyone away empty-handed. A key part of this ritual, known to all, was giving Udi as a parting blessing, signifying his permission for devotees to leave Shirdi and return to their homes.
