I've been praying to see God in a specific form. What do the stories about Sai Baba's devotees teach about having such visions, for example, of Vitthal?

Chapter 4 recounts several instances of devotees having visions of Vitthal. Sai Baba emphasized the role of faith, telling Das Ganu that Vitthal would indeed appear but 'the devotee must be full of faith.' True to his word, Das Ganu received a vision of Vitthal in Shirdi. Similarly, when Kakasaheb Dixit had a vision of Vitthal during meditation, Baba confirmed it by asking, 'Vitthal Patil had come, right?' Baba also advised him to 'Nail him down and make him steady,' suggesting that maintaining such a vision requires constant focus and devotion. These accounts suggest that with intense faith and Baba's grace, such spiritual experiences are possible.
