Can you describe Kakasaheb Dixit's experience related to Vitthal as mentioned in the texts?

Certainly. According to Chapter 4, Kakasaheb Dixit had a profound experience involving Vitthal. While in meditation after his morning bath, he received a vision of the deity. When he later went for Sai Baba’s Darshan, Baba surprisingly confirmed the event, asking, "Vitthal Patil had come, right? Did you meet him?" Baba even added a playful warning to keep Vitthal steady, as he might escape. Later that day, a seller arrived with pictures of Vitthal of Pandharpur, and one image was an exact replication of the form Dixit saw in his meditation. Dixit, amazed by this synchronicity and remembering Baba's words, purchased the picture and installed it for worship.
