Based on Chapter 1, how does the author equate Sai Baba with the principal Hindu deities?

Chapter 1 of the Sai Satcharitra establishes a profound theological foundation by identifying Sadguru Sainath with several principal deities. The author explicitly states, 'This Sai himself is Ganesha Ganapati,' who will destroy obstacles and reveal knowledge. Similarly, the text asserts that 'Sai himself is Goddess Saraswati,' who sings his own life story through the author for the salvation of devotees. Going further, after bowing to the trinity of Brahma, Vishnu, and Shankar, the author addresses Sai directly. As noted in Chapter 1, he says: '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).' This establishes Sai Baba not just as a Guru but as the non-dual embodiment of the divine itself.
