How does Chapter 22 connect the viewing of Sai Baba's foot to the sighting of the moon?

Chapter 22 draws an intricate parallel between a devotee's spiritual longing and the natural anticipation of seeing the crescent moon after the dark New Moon night. The text explains that Baba would fulfill this longing for a divine vision in a specific way. He would sit with his right foot over his left knee and use his left hand to create a gap between his toes. The nail on his right big toe is said to shine like the crescent moon. As described in Chapter 22, a devotee could then fix their gaze through this gap to see the 'moon' of his nail, satisfying their curiosity for a vision in a manner that mirrors watching the sky for the actual moon.
