Can you explain the connection between Baba's Siddhis, the power of 'Anima', and his imperceptible movements mentioned in Chapter 10?

Chapter 10 directly connects Sai Baba's mysterious ability to sleep on a suspended narrow plank to his divine powers, or Siddhis. The text posits that the plank couldn't have physically supported him and was 'merely for name’s sake.' To explain his imperceptible movements, the chapter specifically references the 'Master of Anima.' 'Anima' is the yogic power to become infinitesimally small. By possessing this siddhi, Baba's movements could be as subtle and easy as those of 'flies, insects, or ants,' making it impossible for anyone to perceive how he got on or off the plank. This illustrates that his actions often transcended the laws of physics.
