Based on Chapter 1, analyze the symbolism used to describe Lord Ganesha and how it relates to the author's purpose in writing the Satcharitra.

Chapter 1 of the Sai Satcharitra employs rich symbolism to describe Lord Ganesha, which directly mirrors the author's aspirations for the book. Ganesha is called "Lambodar" (large-bellied) because the fourteen worlds reside in his belly, symbolizing comprehensiveness. He holds a "bright axe" to destroy the obstacles of devotees, representing the author's hope that the book will clear the spiritual obstacles of its readers. Furthermore, the text identifies Ganesha as a "boat to cross the ocean of worldly existence" and a "flame of knowledge in the darkness of ignorance." This symbolism is then directly transferred to Sai Baba himself, who, as Chapter 1 states, is Ganesha and will use his axe to destroy obstacles and bring forth knowledge.
