How did Sai Baba help his devotees Das Ganu and Kakasaheb Dixit experience visions of Vitthal?

Sai Baba facilitated visions of Lord Vitthal for his devotees by responding to their faith. For Das Ganu, who was organizing a Name-week (Saptah), Baba promised that Vitthal would appear if the devotee was full of faith, placing a hand on his chest for emphasis. As chapter 4 describes, at the end of the Saptah, Das Ganu did receive a sight of Vitthal. In a separate instance detailed in chapter 4, after Kakasaheb Dixit had a vision of Vitthal during meditation, Baba confirmed it by asking, "Vitthal Patil had come, right?" Baba then advised him to "nail him down and make him steady," reinforcing the reality of the vision. This was further validated when a seller arrived with pictures of Vitthal that exactly matched what Dixit had seen in his meditation.
