How is Sai Baba's presence described in the scriptures? Is he limited to a physical location?

The scriptures describe Sai Baba's presence as being limitless and all-pervading. According to the account in Chapter 40, Baba's state is inscrutable. He is not confined by physical location, even though his permanent residence was Shirdi. The text explains that the idea of "coming from there to here, or going from here to there" is just worldly talk. Baba is likened to the sky, which is perfectly full, inside and out, and knows no such travel. He pervades the moving and the unmoving and can manifest wherever He wishes by His mere will. This divine quality is why Dev, despite being in distant Dahanu, had full faith that Baba would come to him.
