The text describes Baba's movements as 'imperceptible,' particularly concerning his sleeping plank. How does Chapter 10 explain this phenomenon and his ability to rest on such a fragile structure?

Chapter 10 explains the mystery of Sai Baba's imperceptible movements by attributing them to his divine powers, or Siddhis. The plank he slept on was narrow and hung by fragile rags, making it physically impossible to support his weight through conventional means. The text explicitly states that the plank was for 'name's sake' and his ability to rest there was due to the 'Great Siddhis residing within Him.' To further illustrate this, Chapter 10 introduces the concept of 'Anima,' the power to become minute. It suggests Baba could easily move in the forms of flies, insects, or ants, which is why no one ever witnessed him climbing up to or descending from the plank.
