How does Sai Baba describe his own presence and form? Is he limited to his physical body?

Sai Baba explains that he is not limited to his physical body. In the teachings from Chapter 19, he states his true nature is all-pervading, declaring, 'In water, land, wood, and region; among people, in the forest, in the country and abroad; I am pervaded in light and sky; I am not limited to one place.' He clarifies that he has taken on a physical form of 'three and a half cubits' specifically to help devotees who mistakenly believe he is confined to that body, aiming to free them from this limiting doubt and reveal his omnipresence.
