What is the primary purpose and content of the first chapter of Sai Satcharitra?

The first chapter of Sai Satcharitra, titled 'Mangalacharan', is dedicated to auspicious invocations. As explained within Chapter 1, the primary purpose of these salutations is to ensure the obstacle-free completion of the book and to obtain divine grace. The author begins by offering obeisance to several deities, including Lord Ganesha, Goddess Saraswati, the Hindu trinity of Brahma, Vishnu, and Shankar, and the family deity Narayana. This traditional etiquette is adopted to remove all obstacles and fulfill the desired goal of successfully writing about the life of Sadguru Sainath, who is also invoked and revered throughout.
