What is the primary purpose and structure of the invocations found in Chapter 1 of the Sai Satcharitra?

The first chapter of the Sai Satcharitra is titled Mangalacharan, which means auspicious invocations. The author explains that this traditional practice is performed at the start of any task to ensure its obstacle-free completion and to obtain divine grace. As detailed in Chapter 1, the primary purpose is the removal of all obstacles and the fulfillment of the goal of writing the book. The structure involves offering salutations to several deities in sequence, beginning with Lord Ganesha, followed by Goddess Saraswati, the divine trinity of Brahma, Vishnu, and Shankar, and the family deity, Narayana. A unique aspect highlighted in this chapter is the identification of Sai Baba himself with these deities, establishing a non-dualistic theme from the very beginning.
