Why doesn't the Shri Sai Satcharita mention Saint Francis of Assisi? Was there a reason he was excluded?

The Shri Sai Satcharita does not mention Saint Francis of Assisi by name, so it does not provide a reason for his exclusion. However, the book's preface offers a broader perspective on spiritual guidance. As explained in Chapter 0, the text holds a firm principle that a Sadguru is essential for salvation, but this guide can come in many forms, not limited to a specific person, religion, or age. It could be a saint, a parent, or even a book. The focus is on the principle of Guru grace rather than creating an exhaustive list of all saints.
