How does the first chapter of the Satcharitra draw a parallel between Sai Baba and Lord Ganesha?

Chapter 1 of the Satcharitra explicitly equates Sai Baba with Lord Ganesha, stating that Sai himself is Ganesha Ganapati. The text describes how this Sai, taking an axe in hand, will destroy the obstacles of his devotees and bring forth his own knowledge. He is further identified as the crescent-mooned Ganesha and the formidable destroyer of the forest of obstacles, a compassionate Sai in non-dual form who can lead one to the abode of self-bliss.
