How is Lord Ganesha described in the first chapter, and what is his role in the context of the Sai Satcharitra?

In Chapter 1, Lord Ganesha is described with various epithets, including the curved-trunk Heramba, the auspicious-looking elephant-faced one, and Lambodar (large-bellied) because the fourteen worlds reside in his belly. He holds a bright axe to destroy the obstacles of his devotees. Significantly, the text equates Sai Baba himself with Ganesha, stating that 'This Sai himself is Ganesha Ganapati.' This implies that Sai, taking the axe in hand, will destroy obstacles and bring forth his own knowledge for the devotees, acting as the remover of difficulties for the successful completion and understanding of his life story.
