Why were the works of poet Shri Dasganu Maharaj not considered ideal for a Parayan focusing on a single saint's life?

As explained in Chapter 0, while one can perform a Parayan of Shri Dasganu Maharaj's larger works like Shri Bhaktalilamrut, they are not suitable for a Saptah dedicated to a single saint. The text clarifies that the biographies contained within these collections are not comprehensive or detailed enough for this specific purpose. A particular saint's life story might only span two or three pages, which is insufficient for the kind of in-depth study and recitation involved in a focused Parayan or Saptah.
