What key themes and stories does Chapter 10 of the Shri Sai Satcharitra introduce regarding the Sadguru's nature and lifestyle?

Chapter 10 introduces the supreme power of the Guru and begins to detail Sai Baba's unique lifestyle. It starts by emphasizing that faith in the Sadguru is the easiest path to liberation, capable of changing one's fate and destroying karma. After briefly recapping the previous chapters, Chapter 10 poses a new question about Baba's lifestyle, noting that He was a mother to both Hindus and Muslims, where "the tiger and the lamb lived together." It then introduces the central story of this section: the mystery of how Baba slept on a narrow wooden plank suspended from the rafters, a feat made possible by His divine Siddhis.
