How does Chapter 22 use the moon as a metaphor in relation to Sai Baba's feet?

Chapter 22 beautifully employs the metaphor of the moon to describe a unique aspect of darshan at Sai Baba's feet. The chapter explains that devotees' longing for a vision is like the natural longing for the sight of the moon after the dark night of the New Moon. It then describes how Baba would sit with his right foot over his left knee. The nail of his right big toe, seen through the gap of his fingers, is likened to the shining crescent moon of the second day. This comparison, as detailed in Chapter 22, illustrates how Baba fulfilled the spiritual curiosity of his devotees, allowing them to 'see the moon' at his very feet.
