Based on Chapter 10, what is the significance of the wooden plank and how does it relate to Baba's Siddhis, such as 'Anima'?

The wooden plank mentioned in Chapter 10 is not just a bed but a symbol of Sai Baba's divine powers, or Siddhis. The plank was impossibly narrow and suspended by mere rags, making it physically incapable of supporting a person. The text posits that the plank was "merely for name’s sake" because of the "Great Siddhis residing within Him." The chapter then connects this to the siddhi of 'Anima,' the power to become minute. It notes that while a tiny particle can prick the eye, the Master of 'Anima' can hide there easily. This suggests that Baba's movements could be as subtle and imperceptible as those of flies or ants, explaining why no one ever saw him get on or off the plank and reinforcing his complete mastery over the physical form.
