Can you summarize the key themes introduced in Chapter 10, including Baba's lifestyle and his role as a unifier?

Chapter 10 transitions from the topics of previous chapters to focus on Baba's unique lifestyle and profound spiritual significance. It describes his mysterious sleeping habits on a narrow, suspended wooden plank, which no one saw him mount or dismount. The chapter also emphasizes his role as a great unifier, a 'mother to both Hindus and Muslims,' where the 'tiger and the lamb lived together in trust and love.' Furthermore, it delves into the supreme importance of the Guru, who can change destiny, destroy karma, and grant liberation to devotees who place their faith in Him.
