Why are some biographies of saints, such as those found in Shri Dasganu Maharaj's works, considered unsuitable for a dedicated Parayan?

The text explains that while one can perform a Parayan of Shri Dasganu Maharaj's larger works like Shri Bhaktalilamrut, the individual biographies of saints contained within them are not ideal for a focused, singular Saptah or Parayan. The reason for this, as detailed in Chapter 0, is that these specific biographies are not comprehensive or detailed enough. They often only occupy two or three pages, lacking the depth required for an extensive devotional reading focused on a single saint's life, unlike more detailed works.
