How does Chapter 1 of the Sai Satcharitra establish a non-dual relationship between Sai Baba and the deities being invoked?

Chapter 1 introduces a non-dual philosophy by repeatedly identifying Sai Baba with the very deities being invoked. The text explicitly states, 'This Sai himself is Ganesha Ganapati' and 'Sai himself is Goddess Saraswati.' This theme of oneness is further expanded when the author addresses Sai as the embodiment of the Trimurti, stating, 'you alone are our Lord of Ganas (Ganadhish), the Lord of Savitri (Brahma), the Lord of Rama (Vishnu), or the Lord of Uma (Shiva).' The chapter uses the specific phrase 'compassionate Sai in non-dual form,' directly pointing to the teaching that the Sadguru is the all-encompassing, supreme reality, not separate from the gods.
