In what ways does the author of the Sai Satcharitra equate Sai Baba with the deities being invoked in the first chapter?

A significant theme in Chapter 1 is the identification of Sai Baba with the very deities being worshipped. After the invocation to Ganesha, the text explicitly states, "This Sai himself is Ganesha Ganapati; this Sai, taking the axe in hand and destroying obstacles, shall bring forth his own knowledge." Similarly, after invoking the goddess of learning, Chapter 1 says, "Sai himself is Goddess Saraswati, holding the Omkara-veena in hand, singing his own life story." This identification extends to the Hindu trinity, as the author addresses Sai directly, saying, "O self-effulgent Sainath, you alone are our Lord of Ganas (Ganadhish), the Lord of Savitri (Brahma), the Lord of Rama (Vishnu), or the Lord of Uma (Shiva)."
