How does Chapter 10 connect Sai Baba's physical actions, like sleeping on a plank, to the philosophical concept of the Guru's omnipotence?

Chapter 10 masterfully links Baba's seemingly simple lifestyle choices to profound spiritual truths. The chapter first establishes the Guru as the 'one eternal God' who can change fate and grant liberation. It then presents the story of the sleeping plank not just as a biographical detail but as a demonstration of this very power. His ability to rest on a narrow plank hung by rags, and his imperceptible movements, are explained through his possession of Great Siddhis. This physical feat serves as a tangible manifestation of the abstract philosophical claims made earlier in the chapter, showing that the Guru's power transcends the normal laws of physics and existence.
