According to Chapter 1, what is the role of Goddess Saraswati, and how is she linked to Sai Baba?

Chapter 1 explains that Goddess Saraswati, the daughter of Brahma, is the Goddess of Speech and knowledge, without whose grace no literature can be achieved. She is described as holding the Brahma-veena and riding a swan. The author invokes her so that he may become the instrument to narrate Sai's life. The text then makes a profound connection, stating that 'Sai himself is Goddess Saraswati,' who holds the Omkara-veena and sings his own life story for the salvation of his devotees, thus equating Sai with the very source of knowledge and expression.
