Can you provide a detailed account of a specific Guru's childhood and youth as described in the source?

The provided material does not offer a detailed account of any specific Guru's childhood or youth. While Chapter 0 mentions that a Guru's biography is a reliable book describing their incarnation, childhood, youth, and miracles, it does not provide these specific details for any particular individual. The text is a preface that discusses the genre of Guru biographies, their purpose for study (Parayan), and the distinction between desire-filled (Kamya) and selfless (Nishkam) reading. It also notes that the works of poets like Shri Dasganu Maharaj contain brief, not comprehensive, biographies.
