Can you detail the relationship between Sai Baba and Gajanan Maharaj as described in the introduction?

The provided introductory text from Chapter 0 does not describe any relationship between Sai Baba and Gajanan Maharaj. In fact, Gajanan Maharaj is not mentioned at all. The source material details the arrival of the person who would become known as Sai Baba in Shirdi. It recounts his meeting with Chandbhai, the miracle of finding the horse, and how he came to Shirdi with a wedding party. The passages in Chapter 0 focus on his first encounter with Mhalasapati, who gave him the name "Sai Baba," but no connection to Gajanan Maharaj is documented.
