How does Chapter 22 explain the "logic of the branch and the moon" in relation to seeing Sai Baba?

Chapter 22 of the Shri Sai Satcharitra vividly describes the experience at Sai Baba's feet, introducing the "logic of the branch and the moon." This concept is an analogy for finding a subtle object, like the thin crescent moon in the sky, by using a more obvious reference point, such as looking through a gap between tree branches. The chapter applies this logic to the darshan of Baba's feet. It describes how, when Baba sat with his right foot over his left knee, the nail on his right big toe shone like the crescent moon. Devotees were guided to fix their gaze there, and through this specific focus, they could fulfill their "curiosity for a vision," as mentioned in Chapter 22.
