How is Lord Ganesha described in Chapter 1, and what is his role in the context of the Sai Satcharitra?

According to Chapter 1, Lord Ganesha is invoked as the remover of all obstacles to ensure the successful completion of the work. He is described as the curved-trunk Heramba, the Lord of fourteen types of knowledge, and Lambodar (large-bellied), in whose belly the fourteen worlds reside. He holds a bright axe to destroy the obstacles of his devotees. Significantly, Chapter 1 equates Sai Baba himself with Ganesha, stating that 'This Sai himself is Ganesha Ganapati; this Sai, taking the axe in hand and destroying obstacles, shall bring forth his own knowledge.'
