While the works of poets like Shri Mahipati and Shri Dasganu Maharaj are mentioned, what specific limitation do they have for a devotee wishing to conduct a Parayan of a single saint?

The preface in Chapter 0 acknowledges the famous poets Shri Mahipati and Shri Dasganu Maharaj for their great works compiling the biographies of saints in the Ovi meter. However, it points out a significant limitation. If a devotee wishes to perform a Parayan or Saptah specifically for a single saint, these collections are not ideal. The reason given is that the individual biographies contained within their works are not comprehensive or detailed, often spanning only two or three pages. This brevity makes them unsuitable for a focused, in-depth recitation dedicated to one particular saint.
