Why were earlier biographical writings, such as those by Shri Dasganu Maharaj, considered not ideal for a detailed Parayan of a single saint?

The source material explains the limitations of earlier works for the specific purpose of a detailed Parayan or Saptah. According to Chapter 0, while poets like Shri Dasganu Maharaj included saints' biographies in their collections like 'Shri Bhaktalilamrut', these accounts were not comprehensive. The text states that if one wishes to perform a Parayan focusing on a single saint's life, these biographies are not particularly useful because they are not detailed, often occupying only two or three pages. For a deep, immersive study like a Saptah, a more extensive and singularly focused work like the 'Shri Sai Satcharita' is considered far more suitable and effective.
