Chapter 7 mentions some extraordinary yogic practices Sai Baba performed. Could you describe them?

Chapter 7 of the Shri Sai Satcharitra describes some of Sai Baba's remarkable yogic abilities. It specifically mentions his practice of Khanda-yoga, which involved the disjointing and rejoining of his own limbs. The text states that sometimes his hands, feet, and head would be separated and then joined back together as before. This was one of the extraordinary phenomena, along with experiments like Dhauti (cleansing of the stomach), that demonstrated his complete mastery over his physical body, which he often wore out for the benefit of his devotees.
