What is the primary topic of Chapter 33 of the Sai Satcharitra, and what was Sai Baba's daily practice involving Udi?

Chapter 33 of the Shri Sai Satcharitra primarily focuses on the glory and significance of Udi, or sacred ash. According to the text, Sai Baba maintained a consistent daily practice involving a sacred fire known as the Dhuni. He would purchase bundles of firewood, offer the logs into the Dhuni, and then distribute the resulting ash to his devotees. This was a regular ritual, and Baba would give Udi to visitors in the mornings, afternoons, and evenings. As Chapter 33 explains, he would not send anyone away empty-handed. This Udi was also famously given to devotees as a sign of permission when they sought to leave Shirdi and return to their homes.
