The text mentions some of Sai Baba's unusual yogic practices. Can you describe the miracles or experiments mentioned in Chapter 7?

Chapter 7 describes some of Sai Baba's extraordinary practices, which could be considered miracles. It mentions his practice of Khanda-yoga, which involved the disjointing of his limbs. The text states that sometimes his hands, feet, and head were separated and then joined back together as before. As noted in this chapter, he also performed experiments like Dhauti, which is a method for cleansing the stomach. These practices demonstrate how he wore out his own body and even bore the sufferings of his devotees for their benefit.
