How did Sai Baba use digital media or modern technology to spread his teachings about the Bhagavat?

The source material from Chapter 18 contains no information about Sai Baba using digital media or modern technology, as these did not exist during the time described. Instead, the chapter illustrates Baba's traditional and deeply personal methods for spiritual instruction. He would assign a devotee, such as Bapusaheb Jog, to read from physical, divinely inspired books like the Nath Bhagawat and Jnaneshwari. These readings, or 'Parayana', took place daily in a physical location called Sathe's Wada. As detailed in Chapter 18, Baba would personally direct devotees to go to the Wada to listen, and the experience was intimate, with listeners gathering to hear the explanations and stories. Baba's method involved his own power and grace to orchestrate these learning opportunities, not technological means.
