Based on Chapter 1, what is the traditional reason for performing auspicious invocations, and how is this tradition applied in the Sai Satcharitra?

As explained in the opening of Chapter 1, the wise perform auspicious invocations, or 'Mangalacharan,' at the start of any task for its obstacle-free completion and to obtain divine grace. The stated purpose is the removal of all obstacles and the fulfillment of the desired goal. In the Sai Satcharitra, this tradition is applied by offering salutations to Lord Ganesha, Goddess Saraswati, the Hindu trinity (Brahma, Vishnu, Shankar), and the family deity. This auspicious beginning is meant to ensure the successful writing and sharing of Sai Baba's life story for the benefit of devotees.
