According to the invocations in Chapter 1, how is Sai Baba related to the Hindu trinity of Brahma, Vishnu, and Shiva?

Chapter 1 of the Sai Satcharitra establishes a deep connection between Sai Baba and the Hindu trinity. After bowing to the creators of creation, preservation, and destruction—Brahma, Vishnu, and Shankar, who represent the qualities of Rajas, Sattva, and Tamas—the author directly addresses Sai. As the text of Chapter 1 proclaims, the author sees Sai as the embodiment of all three, stating, "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 highlights the author's belief in Sai as the ultimate, all-encompassing deity.
