How was it possible for Baba to sleep on such a flimsy plank, and what explanation does the book give?

Chapter 10 explains that the narrow wooden plank, tied with mere rags, could not have supported Baba's weight through normal means. The text posits that this was possible due to the Great Siddhis (divine powers) that resided within him. The plank was described as being there "merely for name’s sake." The chapter specifically mentions the 'Anima' siddhi, which is the power to become minute. It suggests that Baba's movements could have been as subtle and easy as those of flies, insects, or ants, allowing him to ascend and descend from the plank without anyone ever noticing.
