Can you explain the extraordinary yogic practices Sai Baba was known for, as mentioned in Chapter 7?

According to Chapter 7 of the Shri Sai Satcharitra, Sai Baba engaged in several remarkable yogic practices that demonstrated his mastery and detachment from the physical body. The text specifically mentions his practice of Khanda-yoga, which involved the supernatural ability to disjoint his limbs—separating his hands, feet, and head—and then rejoining them as they were before. Additionally, the chapter notes his use of cleansing experiments like Dhauti and Poti. These practices highlight how Baba toiled for the benefit of others and even bore the sufferings of his devotees, sometimes wearing out his own body in the process.
