The text mentions Sai Baba possessed 'Great Siddhis' and the power of 'Anima.' How does Chapter 10 use his sleeping habits to illustrate these powers?

Chapter 10 uses the seemingly impossible act of Sai Baba sleeping on a narrow, suspended plank to demonstrate his 'Great Siddhis' or divine powers. The plank was only a span wide and hung by fragile rags, making it physically incapable of supporting a person. The text posits that the plank was "merely for name’s sake" and that Baba’s ability to rest there was a display of his powers. The chapter specifically references the power of 'Anima,' the yogic siddhi of becoming infinitesimally small. It suggests that Baba's movements were as easy and imperceptible as those of flies or ants, which is why no one ever saw him ascend or descend from the plank, thus providing a concrete example of his extraordinary capabilities.
