What specific yogic practices or miracles of Sai Baba are mentioned in the seventh chapter?

Chapter 7 describes some of Sai Baba's extraordinary yogic abilities, particularly his practice of Khanda-yoga. This is explained as a miraculous process where he could disjoint his limbs, separating his hands, feet, and head from his body, and then join them back together as before. The text also briefly mentions other esoteric practices like Dhauti, which is a method for cleansing the stomach. These accounts are presented to illustrate his supernatural control over his physical body and to highlight how he toiled and even bore the sufferings of his devotees, which in itself was a continuous miracle of compassion.
