What were the extraordinary physical or yogic practices attributed to Sai Baba in Chapter 7?

The introductory section of Chapter 7 mentions some of Sai Baba's remarkable yogic abilities, which demonstrated his spiritual mastery and willingness to bear suffering for others. The text describes his practice of 'Khanda-yoga,' which involved the supernatural ability to disjoint his limbs and head and then rejoin them as before. In addition to this, Chapter 7 mentions other esoteric practices such as 'Dhauti' (a method of cleansing the stomach) and 'Poti'. These accounts are presented as examples of how Baba wore out his own body for the benefit of his devotees, underscoring his immense compassion and spiritual power.
