How does Chapter 22 describe the connection between Sai Baba's feet and the moon?

Chapter 22 draws a beautiful parallel between seeing the moon and having a vision of Sai Baba's feet. It describes how devotees longed for a vision, much like people long to see the crescent moon after the dark night of the New Moon. The chapter explains that Baba would fulfill this longing when he sat with his right foot over his left knee. In this posture, the nail on his right big toe would shine "like the second day's moon." This imagery is connected to the logic of the "branch and the moon," where focusing on the big toe allows one to fulfill their curiosity for a divine vision.
