How does Chapter 22 describe the posture of Sai Baba and the significance of his big toe for devotees?

Chapter 22 provides a beautiful and detailed description of Sai Baba's posture and its significance. It explains that Baba would often sit with his right foot placed over his left knee. Devotees' longing for a divine vision is compared to people eagerly awaiting the sight of the crescent moon after the dark night of the New Moon. The chapter states that Baba fulfilled this longing at his own feet. He would grasp the space between his toes with the index and middle fingers of his left hand, and near the right big toe, the 'moon of the nail' would shine like the new moon. This imagery, found in Chapter 22, is further amplified by the story of Das Ganu, where the big toe itself becomes the holy confluence of Prayag, manifesting Ganga and Yamuna and showcasing its immense spiritual power.
