Can you describe Sai Baba's daily practice concerning the Dhuni and the distribution of Udi as detailed in Chapter 33?

As detailed in Chapter 33, Sai Baba's daily practice with Udi was a central part of his routine in Shirdi. He maintained a constantly burning sacred fire, the Dhuni, in the Masjid. He would pile up heaps of firewood logs and offer them into this fire. The ash that remained in great quantity from the burnt logs was the sacred Udi. The chapter states it was his regular custom to distribute this Udi to devotees. He would not send anyone away empty-handed, giving it out in the mornings, afternoons, and evenings. This practice of giving Udi was a consistent, daily ritual that all devotees were familiar with.
