How did Sai Baba show his connection to Lord Vitthal for devotees like Das Ganu and Kakasaheb Dixit?

Sai Baba demonstrated his profound connection to Lord Vitthal through miraculous experiences granted to his devotees. As described in Chapter 4, when Das Ganu organized a Name-week (Saptah) and requested a vision of Vitthal, Baba assured him that Vitthal would indeed appear, provided the devotee was full of faith. True to his word, Das Ganu received a vision of Vitthal in Shirdi. Similarly, Kakasaheb Dixit experienced a vision of Vitthal during his morning meditation. When he went to see Baba later, Baba surprised him by asking if "Vitthal Patil had come," thus confirming the authenticity of his inner experience. These incidents showed that Baba could manifest or validate visions of other deities for his followers, reinforcing their faith.
