What does Chapter 7 say about Sai Baba's practice of Khanda-yoga and other mysterious abilities?

The beginning of Chapter 7 mentions some of Sai Baba's extraordinary and mysterious practices, which he used for the benefit of others and to bear the sufferings of his devotees. The text specifically refers to his practice of Khanda-yoga, which is described as the disjointing of his limbs. During this state, which was associated with his Samadhi, his hands, feet, and head would be separated from his body and then joined back together as before. The chapter also briefly mentions other similar experiments he performed, such as Dhauti (a yogic cleansing of the stomach) and Poti, showcasing the incredible and often incomprehensible ways he would toil for the welfare of others.
