I'm looking for information on Saint Augustine. Since the book discusses writing biographies of saints as a form of Guru service, where can I find the details on him?

The source text, specifically the Preface found in Chapter 0, discusses the general concept of writing biographies of saints as a form of spiritual Guru service. It contrasts this with worldly service and positions it as a spiritually fruitful act. However, the text's purpose is to explain the principles of Guru service, not to serve as a comprehensive collection of saint biographies. It does not mention Saint Augustine or any other specific saints from Western traditions. The only saintly figure it quotes is Dnyaneshwar Maharaj, in the context of his commentary on the Gita. Therefore, there is no information about Saint Augustine in the provided text.
