The introduction to Chapter 7 mentions several of Sai Baba's extraordinary abilities. Could you elaborate on these practices, such as Khanda-yoga?

Chapter 7 of the Shri Sai Satcharitra provides a glimpse into Sai Baba's remarkable spiritual practices. The text highlights his practice of Khanda-yoga, which involved the disjointing and rejoining of his limbs, as well as experiments like Dhauti, which is a cleansing of the stomach. These descriptions illustrate the extent to which he toiled for others, even bearing the sufferings of his devotees and wearing out his own body. The chapter portrays these abilities as part of his extraordinary nature, which was beyond easy categorization.
