From the provided text, describe Baba's daily ritual concerning firewood and the sacred fire.

The daily ritual concerning firewood and the sacred fire is described in Chapter 33. Sai Baba would perform charitable deeds, including buying bundles of firewood from those who had a surplus. He would then pile up these heaps of dry logs. The next step in this daily practice was to offer these logs into the sacred Dhuni, or fire, that he kept constantly burning in front of him in the Masjid. This continuous fire would produce a great quantity of ash, which was known as Udi. Baba would then collect this Udi and distribute it to devotees, a practice that was a constant feature of his day.
