What are the recommended ways for a group of followers to collectively engage with a saint's biography, and why are some texts not suitable for this?

According to the information presented in Chapter 0, a powerful way for a congregation of devotees to engage is by performing a Parayan or Saptah, which involves the collective study and recitation of a detailed poetic biography. This practice allows devotees to achieve the purpose of their lives. However, not all texts are suitable for this. Some biographies, like those found in Shri Dasganu Maharaj's works, are not comprehensive or detailed enough, often spanning only two or three pages. For a successful group Parayan, a detailed, poetic, and comprehensive work is necessary.
