How did Sai Baba's posture, as mentioned in Chapter 22, help devotees experience a divine vision?

Chapter 22 of the Shri Sai Satcharitra describes a specific posture Sai Baba would assume to fulfill the spiritual longings of his devotees. He would sit with his right foot placed over his left knee. The text compares the nail of his right big toe to the crescent moon seen after the dark night of the New Moon. For those whose 'curiosity for the vision is great,' this chapter explains they were guided to look through the gap formed by Baba's fingers near the toe. This act of focused gazing, similar to the 'logic of the branch and the moon,' allowed them to perceive the divine, with the nail of the big toe shining like the second day's moon.
