Based on the first chapter, describe the key attributes and role of Lord Ganesha.

Chapter 1 of the Shri Sai Satcharitra provides a rich description of Lord Ganesha's attributes and his primary role as the remover of obstacles. He is invoked as the "curved-trunk Heramba," the "Lord of fourteen types of knowledge," and the "auspicious-looking elephant-faced one." His name Lambodar (large-bellied) is explained by the concept that the fourteen worlds reside within his belly. According to Chapter 1, he holds a bright axe to destroy the obstacles of his devotees, and obstacles are said to crumble at his very feet. He is also hailed as the "boat to cross the ocean of worldly existence" and the "flame of knowledge in the darkness of ignorance," showcasing his divine power.
