How does Chapter 22 describe the way devotees could see the 'moon' at Sai Baba's feet?

Chapter 22 details a unique method for devotees to receive a divine vision, using the 'logic of the branch and the moon,' where a nearby object is used to point to a distant one. The text explains that just as people long to see the new moon after a dark night, devotees longed for a divine vision. Baba fulfilled this by having them focus on his foot. As described in Chapter 22, he would sit with his right foot over his left knee and grasp his right big toe with the index and middle fingers of his left hand. Devotees were told to gaze through the gap, where the 'moon of the nail' on his big toe would shine like the crescent moon, fulfilling their desire for a vision.
