The preface mentions several authors and their works. How does it distinguish between the works of Mahipati and Dasganu Maharaj and the works like Guru Charitra and Shri Sai Satcharita?

According to Chapter 0, while poets like Shri Mahipati Maharaj and Shri Dasganu Maharaj wrote significant collections of saints' biographies, such as Shri Bhaktalilamrut, these works are not ideal for a dedicated devotional reading (Parayan or Saptah) of a single saint. The reason given is that the individual biographies within these collections are often very brief, sometimes only two or three pages long. In contrast, the preface highlights two works as being exceptionally detailed, comprehensive, and suitable for such devotional practices: the Guru Charitra by Shri Saraswati Gangadhar and the Shri Sai Satcharita by Shri Annasaheb Dabholkar. These are presented as rare examples of extensive poetic Guru biographies in Maharashtra.
