Why are some of Dasganu Maharaj's works, like Shri Bhaktalilamrut, considered not ideal for a Parayan of a single saint's life?

While poet Shri Dasganu Maharaj's works, such as Shri Bhaktalilamrut and Shri Bhaktisaramrut, are mentioned, the text in Chapter 0 clarifies their limitation for a specific type of devotional practice. If a devotee wishes to perform a Parayan or Saptah focusing exclusively on the biography of a single saint, these works are not considered useful. The reason provided is that the biographies within them are not comprehensive or detailed, often spanning only two or three pages. This lack of depth makes them unsuitable for the immersive, dedicated study that a Parayan of a single saint's life requires.
