How does Chapter 10 use the example of the sleeping plank to illustrate Sai Baba's divine powers, or Siddhis?

Chapter 10 uses the sleeping plank as a powerful illustration of Sai Baba's divine Siddhis. The text questions how such a narrow plank, merely a span wide and tied with flimsy rags, could possibly support Baba's weight. The narrative concludes that the plank was 'merely for name’s sake' because 'Great Siddhis (powers) resided within Him.' This implies his abilities transcended physical laws. The chapter further elaborates on this by mentioning the 'Anima' siddhi, the power to become minute, suggesting that Baba's movements could be as subtle and imperceptible as those of flies, insects, or ants. The entire episode serves to demonstrate that Baba's actions were not bound by ordinary human limitations but were expressions of his divine powers.
