How does Chapter 1 establish the non-dual identity between Sai Baba and various Hindu deities?

Chapter 1 of the Sai Satcharitra establishes a non-dual identity between Sai Baba and several prominent deities through direct statements and comparisons. For instance, the text explicitly declares, 'This Sai himself is Ganesha Ganapati,' who destroys obstacles. It then refers to Sai as the 'compassionate Sai in non-dual form' with Ganesha. Similarly, after invoking Goddess Saraswati, the chapter states, 'Sai himself is Goddess Saraswati, holding the Omkara-veena in hand.' The author also 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),' thereby equating him with the Hindu trinity.
