Based on Chapter 22, what was Sai Baba's unique way of fulfilling his devotees' longing for a vision?

According to the narrative in Chapter 22, Sai Baba had a unique method for satisfying the deep longing his devotees felt for a divine vision, or darshan. The text compares their intense yearning to the way people eagerly look for the new moon after the dark night of the New Moon. To fulfill this spiritual curiosity, Baba would often sit with his right foot over his left knee. As Chapter 22 details, he would then have devotees fix their gaze upon his right big toe. The nail of this toe was said to shine like the crescent moon, providing a tangible focal point through which they could experience a divine vision and find spiritual happiness at his feet.
