Which limitation is cited regarding the works of poet Shri Dasganu Maharaj when wanting to perform a Parayan for a single saint?

While the works of poet Shri Dasganu Maharaj, such as Shri Bhaktalilamrut and Shri Bhaktisaramrut, are valuable, a specific limitation is noted in Chapter 0. If a devotee wishes to perform a Parayan or Saptah focused specifically on the biography of a single saint, these works are described as not being useful for that purpose. The reason provided is that the biographies within them are not comprehensive or detailed, often taking up only two or three pages, which is insufficient for an in-depth devotional study of one saint's life.
