What advanced yogic practices of Sai Baba, involving physical control and separation of limbs, are mentioned in the Satcharitra?

The introduction to Chapter 7 of the Shri Sai Satcharitra mentions some of Sai Baba's extraordinary and intense yogic abilities, which he used for the benefit of others. The text specifically refers to his practice of Khanda-yoga, which is described as the disjointing of his own limbs. It states that his hands, feet, and head could be separated and then joined back together as before. In addition to this remarkable feat, the chapter notes his use of other yogic experiments like Dhauti, which is a method for cleansing the stomach, and Poti. These practices highlight his incredible physical control and his willingness to bear suffering.
