Can you summarize the tradition of writing Guru biographies in Marathi literature based on the provided text?

The text from Chapter 0 outlines a significant tradition of composing Guru biographies in Marathi. It mentions that this practice is ancient, citing the Narada Purana. Specifically within Marathi literature, it highlights the famous poet Maharaj Shri Mahipati, who wrote biographies of saints in the Ovi meter in his works, Shri Bhaktalilamrut and Shri Santalilamrut. Similarly, the poet Shri Dasganu Maharaj composed brief biographies of more recent Maharashtrian saints. However, the text also notes a limitation: these biographies are often too brief, spanning only a few pages, making them less suitable for a comprehensive, week-long devotional reading, or Saptah.
