What are the main deities invoked in the first chapter of Sai Satcharitra and what is their significance?

The first chapter of the Sai Satcharitra, the 'Mangalacharan', features invocations to several key deities to ensure the book's auspicious and successful completion. The chapter begins with salutations to Lord Ganesha, who is revered as the remover of all obstacles. Next, the author bows to Goddess Saraswati, the goddess of speech and knowledge, seeking her grace to write the literature. The chapter also includes salutations to the trinity of Brahma, Vishnu, and Shankar—the creators of creation, preservation, and destruction. Finally, the author pays respect to the family deity, Narayana, the primordial Lord. As Chapter 1 explains, these invocations are a traditional and wise practice for fulfilling a desired goal.
