How does Chapter 22 describe the fulfillment of devotees' longing for a vision by using the analogy of the moon?

Chapter 22 beautifully describes how Sai Baba fulfilled the spiritual longing of his devotees. The text draws a parallel between the natural eagerness everyone feels to see the crescent moon after the dark New Moon night and a devotee's yearning for a divine vision. The chapter explains that Baba would fulfill this longing at his own feet. When he sat with his right foot over his left knee, the moon of his toenail would shine. As the text details, devotees were told to fix their gaze where the index and middle fingers of his left hand grasped his toes, and through that gap, the nail of the right big toe would appear like the crescent moon, satisfying their curiosity and desire for a vision.
