What is the primary purpose of the Mangalacharan (invocations) described at the start of Chapter 1 of the Sai Satcharitra?

The primary purpose of the Mangalacharan, or auspicious invocations, at the beginning of Chapter 1 is to ensure the obstacle-free completion of the task of writing the book. The author explains that this is a traditional practice performed by the wise to remove all obstacles and obtain the grace of the desired deity for the fulfillment of their goal. As detailed in Chapter 1, these invocations begin with a salutation to Lord Ganesha, the remover of obstacles, and extend to other deities, all with the aim of seeking divine assistance and blessings for the successful creation of the Shri Sai Satcharitra.
