In what ways does Chapter 1 equate Sai Baba with the deities being invoked?

Chapter 1 of the Sai Satcharitra repeatedly equates Sai Baba with the very deities being invoked. For instance, after invoking Ganesha, the text states, 'This Sai himself is Ganesha Ganapati; this Sai, taking the axe in hand and destroying obstacles, shall bring forth his own knowledge.' Similarly, after the prayer to Goddess Saraswati, it says, 'Sai himself is Goddess Saraswati, holding the Omkara-veena in hand, singing his own life story.' The author further addresses Sai directly as the embodiment of the trinity, 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).'
