Chapter 1 identifies Sai Baba with multiple deities. Can you explain which ones and what this signifies?

Chapter 1 of the Shri Sai Satcharitra emphasizes the non-dual nature of Sai Baba by identifying him with several key deities. The text explicitly states that Sai is Ganesha, the remover of obstacles. It also equates him with Goddess Saraswati, the source of knowledge and speech. Furthermore, after bowing to the Hindu trinity of Brahma, Vishnu, and Shankar (Shiva), 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).' This signifies that, for the devotee, Sai Baba embodies the functions and forms of all major deities, acting as the ultimate Sadguru.
