How did Sai Baba help his devotees get visions of Lord Vitthal?

Sai Baba facilitated visions of Lord Vitthal by emphasizing the importance of faith. According to Chapter 4, when he ordered Das Ganu to organize a Name-week (Saptah), Baba promised that the form of Vitthal would appear, but stressed that "the devotee must be full of faith." Indeed, Das Ganu was blessed with a sight of Vitthal in Shirdi. In another instance, after Kakasaheb Dixit had a vision of Vitthal in meditation, Baba confirmed it by asking if "Vitthal Patil had come." The experience was solidified when a seller arrived with pictures of Vitthal that exactly matched Dixit's vision, proving Baba's omnipresence and his ability to grant such divine experiences.
