Can you explain the concept of Sai Baba's imperceptible movements as detailed in Chapter 10, including the powers mentioned?

Chapter 10 delves into the mysterious nature of Sai Baba's movements, particularly in relation to his sleeping plank. It states that no one ever saw him get on or off the narrow plank that was hung from the ceiling. The chapter explains that this was possible due to the "Great Siddhis" (divine powers) he possessed. Specifically, it mentions the Siddhi of 'Anima,' which is the power to become minute. This power allowed Baba to move with the ease of flies, insects, or ants, making his actions imperceptible. This detail from Chapter 10 illustrates that his physical actions were often manifestations of his divine capabilities, not bound by ordinary physical laws.
