Describe how Sai Baba facilitated visions of Vitthal for his devotees and what lesson he taught through them.

As recounted in Chapter 4, Sai Baba facilitated visions of Vitthal for several devotees, emphasizing that faith was the key. When Das Ganu was organizing a Name-week (Saptah), Baba placed a hand on His chest and assured him that Vitthal would appear, provided the devotee was full of faith, and indeed Das Ganu is said to have received a vision. Similarly, when Kakasaheb Dixit had a vision of Vitthal in meditation, Baba confirmed it by asking if 'Vitthal Patil' had visited. Baba then advised him to 'nail him down and make him steady,' implying that one must hold onto such divine experiences with unwavering focus. This was further proven when a seller arrived with pictures of Vitthal that perfectly matched Dixit's vision, reinforcing the reality of the spiritual experience.
