Why does the author of the Sai Satcharitra begin with a series of invocations in Chapter 1?

The author begins the Shri Sai Satcharitra with a series of invocations, known as 'Mangalacharan,' adhering to a wise and traditional etiquette. As explained in Chapter 1, the primary reason for this auspicious beginning is to ensure the obstacle-free completion of the task of writing the book. The purpose is twofold: to remove all potential hindrances and to obtain the grace of the desired deities for the fulfillment of the goal. The author offers salutations to Ganapati, the destroyer of obstacles; Saraswati, the goddess of knowledge; the Hindu trinity; and the family deity. This practice is adopted, as Chapter 1 mentions, 'for attaining auspiciousness' and ensuring the successful narration of Sai Baba's life and teachings for the benefit of all devotees.
