How does Chapter 10 reconcile Sai Baba's physical existence, like His sleeping on a plank, with His divine, formless nature as Brahman?

Chapter 10 masterfully illustrates the duality of Sai Baba's nature. On one hand, it describes his physical life, including his unusual sleeping arrangement on a narrow wooden plank just four cubits long, tied with rags. On the other hand, the chapter begins by stating that the Guru is "eternally situated in the form of Brahman." It reconciles these two aspects by explaining that His physical actions were manifestations of His divine powers (Siddhis). The plank, for instance, could not have supported a normal person's weight and was thus "merely for name’s sake." His imperceptible movements suggest His ability to transcend physical limitations, showcasing how the divine Brahman can operate within a human form.
