Chapter 7 mentions some of Baba's extraordinary physical abilities. Can you describe his practice of Khanda-yoga?

Chapter 7 describes some of Sai Baba's remarkable yogic practices, which included Khanda-yoga. This practice involved the disjointing of his limbs, where his hands, feet, and head would be separated from his body and then joined back together as they were before. The text notes that he also performed experiments like Dhauti, which is a cleansing of the stomach. These incredible feats were not for show; the chapter explains that he toiled for the benefit of others, wore out his own body, and even bore the sufferings of his devotees, suggesting these practices were part of his spiritual work and compassion.
