How does Chapter 22 describe Sai Baba's physical form as a means for devotees to experience the divine?

Chapter 22 beautifully illustrates how Sai Baba's physical form served as a gateway to divine experience. It specifically focuses on his feet, describing a posture where he sat with his right foot over his left knee. The chapter notes that the nail of his right big toe 'shines like the second day's moon,' fulfilling the devotees' longing for a divine vision, much like the longing for the moon after a dark night. The text mentions the 'logic of the branch and the moon,' suggesting that just as one points to a branch to locate the moon, devotees could gaze at Baba's toe to perceive the divine, making the celestial accessible through his immediate presence.
