I'm trying to understand how people were drawn to Baba. Was it always their own decision, or did Baba play a role in bringing them to him?

According to Chapter 35, Sai Baba played a very active role in drawing people to him. The text states, "It is Baba himself who gives them the inspiration; only then do they step out." This suggests that the initial impulse to visit Shirdi often originated from Baba's own divine will. He would stimulate a person's natural disposition and guide them toward the spiritual path. The story of Boss Dharamsee illustrates this. Although he came with a curious and critical mindset, his journey ultimately led to a profound transformation. As Chapter 35 narrates, after experiencing the miracle of the seedless grapes, his "previous resolves vanished" and a deep "love for Sai arose in his heart," cementing his desire to be part of the Shirdi community.
