Can you describe the miraculous and enigmatic nature of Sai Baba's physical form and practices as presented in Chapter 7?

Chapter 7 of the Shri Sai Satcharitra portrays Sai Baba as an extraordinary and enigmatic incarnation whose physical form and practices defied conventional understanding. The chapter mentions his practice of Khanda-yoga, a miraculous state where his limbs, head, and feet could be separated and then rejoined. His physical appearance was equally paradoxical; if called a Hindu, he looked like a Muslim, and if called a Muslim, he had pierced ears like a Hindu but also showed signs of circumcision. This chapter emphasizes that his holy incarnation was beyond the simple labels of Hindu or Muslim, a mystery that left even the wisest observers silent and humble.
