How is Lord Ganesha described in the invocations of Chapter 1, and what is his connection to Sai Baba?

In the first chapter of the Shri Sai Satcharitra, Lord Ganesha is invoked as the remover of obstacles. He is described with various names and attributes, including the curved-trunk Heramba, the Lord of fourteen types of knowledge, 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, Chapter 1 directly equates Sai Baba with Ganesha, stating, 'This Sai himself is Ganesha Ganapati.' It further elaborates that Sai, taking the axe in hand, will destroy obstacles and bring forth his own knowledge, identifying him as the compassionate Sai in non-dual form who can lead devotees to the abode of self-bliss.
