Describe the specific interaction between Sai Baba and Ramgir Buwa when the plan to send Udi to Jamner was set in motion.

Chapter 33 provides a detailed account of this interaction. Ramgir Buwa, intending to visit his village in Khandesh, approached Baba at the Masjid to seek permission as was the custom. He bowed, touched Baba's feet, and requested leave, asking for Udi and blessings. Baba responded with loving sentiment, calling him 'Bapugir.' He granted permission but rerouted the devotee's journey, instructing him, 'First go to Jamner; stop there at Nana's house.' Baba then arranged for a message, the Aarti, to be sent to Nana through Gosavi's hand. Finally, as mentioned in Chapter 33, Baba gave him some Udi and a specially prepared bundle of it to deliver to Nana in Jamner.
