Why are the works of Shri Dasganu Maharaj, such as Shri Bhaktalilamrut, not considered ideal for a Parayan of a single saint's life?

While the works of poet Shri Dasganu Maharaj, specifically Shri Bhaktalilamrut and Shri Bhaktisaramrut, are mentioned as significant, Chapter 0 clarifies their limitations for certain devotional practices. If a devotee wishes to perform a Parayan or Saptah focused on a single saint's biography, these works are not ideal because the biographical sections they contain are not comprehensive or detailed. The text states that these life stories often take up only two or three pages, which is insufficient for the in-depth study and immersion that a full Parayan of a single Guru requires.
