How does Chapter 22 describe Sai Baba's physical posture and the significance of his big toe?

Chapter 22 provides a vivid description of how Sai Baba would sit and how his form was an object of meditation for devotees. The text mentions he would sit with his right foot placed over his left knee. A unique analogy is drawn between his big toe and the crescent moon. The longing to see the new moon after a dark night is compared to the devotee's longing for a divine vision. The chapter explains that the nail on Baba's right big toe shone like the second day's moon. This sight, it is suggested, fulfills the devotee's curiosity for a vision, turning a part of the Guru's physical form into a profound spiritual symbol, as confirmed by the story of Das Ganu in the same chapter.
