Can you explain the story of Chand Patil and his role in Sai Baba's arrival in Shirdi as detailed in Chapter 39?

Chapter 39 recounts that Sai Baba first appeared in the Nizam State under a mango tree. His journey to Shirdi happened unexpectedly when he joined the wedding party of Dhupkheda. A man named Chand Patil is identified as the one who initially "found this treasure (Sai)." The chapter alludes to a prior story of how Patil lost his horse, met Sai, was offered a chillum to smoke by him, and then found his horse. Later, as this same chapter explains, a marriage for Chandbhai's nephew was arranged in Shirdi, and the wedding party, including Sai, came to the village for the ceremony.
