What is the primary focus of the first chapter of Shri Sai Satcharitra, and why is it structured in this manner?

The first chapter of Shri Sai Satcharitra is primarily focused on 'Mangalacharan,' which are auspicious invocations to various deities. As explained in Chapter 1, this traditional practice is performed at the beginning of a task to ensure its completion without obstacles and to obtain divine grace. The author offers salutations to Lord Ganesha, Goddess Saraswati, the Guru, and Sadguru Sainath. The purpose of this auspicious beginning is explicitly stated as the removal of all hindrances and the fulfillment of the desired goal, which in this case is the successful writing of the Satcharitra.
