The Satcharitra mentions some unusual yogic practices Baba performed. Can you tell me what they were and what they involved, based on Chapter 7?

According to Chapter 7 of the Shri Sai Satcharitra, Sai Baba engaged in some profound and intense yogic practices that demonstrated his mastery over the physical body. The text specifically mentions His practice of Khanda-yoga, which is described as the disjointing of His limbs. In addition to this, He performed experiments like Dhauti, which involved cleansing the stomach, and Poti. The scripture notes that during these states, His hands, feet, and head were sometimes separated and then joined back together as they were before, highlighting his extraordinary spiritual capabilities.
