How does the first chapter of the Satcharitra establish a connection between Sai Baba and Lord Ganesha?

Chapter 1 of the Sai Satcharitra establishes a profound and direct connection between Sai Baba and Lord Ganesha. After the initial salutations to Ganesha as the remover of obstacles, the text makes the explicit declaration: "This Sai himself is Ganesha Ganapati." It further elaborates on this identity by stating that Sai, taking an axe in hand like Ganesha, will destroy obstacles and bring forth his own knowledge. The chapter reinforces this by attributing Ganesha's qualities to Sai, referring to him as the crescent-mooned, one-tusked, and formidable destroyer of the forest of obstacles, presenting Sai as the compassionate, non-dual form of Ganapati.
