What unusual yogic abilities and physical practices of Sai Baba are mentioned in Chapter 7?

Chapter 7 provides a glimpse into some of Sai Baba's extraordinary yogic abilities. It mentions his practice of Khanda-yoga, which is described as the disjointing of his own limbs. The text states that he would perform experiments like Dhauti (a cleansing of the stomach) and Poti, where his hands, feet, and head were sometimes separated from his body and then joined back together as before. This was part of how he toiled for others, wore out his own body, and even bore the sufferings of his devotees, showcasing his mastery over the physical form.
