What did Nana Chandorkar explain about the role of Sai Baba's will in attracting devotees?

Nana Chandorkar explained to Kakasaheb Dixit that being drawn to Shirdi was not a matter of one's own volition, but a direct result of Sai Baba's grace. Chapter 51 relays Nana's explanation that Baba has a constant promise to his devotees: "No matter how far my person is, even if beyond the seven seas, I tie a string like a sparrow and pull them here immediately." Nana emphasized that "without Baba's will, one cannot be drawn to Him." He presented this as a great sign, suggesting that the very opportunity to get Sai's darshan is proof that the devotee already belongs to Him in some way.
