What were the specific yogic practices of Khanda-yoga, Dhauti, and Poti that Sai Baba performed, and for what purpose, according to Chapter 7?

Chapter 7 describes Sai Baba engaging in highly advanced and unusual yogic practices. It explicitly mentions Khanda-yoga, which is described as the ability to disjoint His own limbs. The text also refers to experiments like Dhauti, a cleansing of the stomach, and Poti, where His hands, feet, and head were said to be separated and then reattached. The purpose of these incredible feats, as implied in Chapter 7, was not for show but was a part of how He toiled for the benefit of others. The chapter states that He wore out His own body and even bore the sufferings of His devotees, suggesting these practices were linked to His deep compassion and spiritual work.
