I asked about Saint Francis of Assisi and you didn't have an answer. Does this mean the book is only focused on Hindu deities and Muslim fakirs?

The Shri Sai Satcharitra focuses on the life and teachings of Sai Baba, and therefore may not name every saint from other traditions, like Saint Francis of Assisi. However, its message is universal. Chapter 19 teaches that the sense of difference, such as 'I and Thou,' is a wall between Guru and disciple that must be torn down to achieve non-duality. Baba's teaching 'Allah-Malik' (God is the Master) signifies that there is one ultimate protector whose deeds are incomprehensible. The book encourages us to focus on our own actions and devotion, as stated in the principle from Chapter 19, 'As the action, so the hearing; as the practice, so the benefit.'
