Can you describe the specific 'leelas' or 'incomparable miracles' that are detailed in this preface?

While the preface in Chapter 0 states that a Guru's biography is a book that describes the Guru's "wonderful plays (Leelas)" and "incomparable miracles," it does not actually provide any specific examples of these events. The text is defining the genre of spiritual biographies and explains their function, rather than narrating the content of one. Therefore, although the concepts of 'leelas' and 'miracles' are mentioned as components of these biographies, no particular stories or details about them are present in these excerpts.
