Who was Devidas, and what was his role in Shirdi as mentioned in Chapter 5?

Chapter 5 introduces Devidas as a wise individual who had settled in Shirdi twelve years before Sai Baba returned with the wedding party. He lived a simple life at the Maruti temple, wearing only a loincloth. Devidas was a respected teacher; he taught Appa Bhill using a slate and made many people memorize the Venkatesh Stotra, conducting lessons regularly. His wisdom was so recognized that Tatyaba took him as a Guru, and other leading disciples revered him. The chapter also recounts how Devidas defeated a visiting Fakir in a scriptural debate, showcasing his spiritual authority in the village at that time.
