Why is a detailed biography like the Shri Sai Satcharita considered more effective for community practices like a Saptah compared to other writings?

The source material explains the value of comprehensive biographies for community devotion. While poets like Shri Dasganu Maharaj wrote about saints, their biographies within larger works were often not detailed, sometimes spanning only two or three pages. Chapter 0 clarifies that for performing a Parayan or Saptah focused on a single saint, such brief accounts are not as useful. A detailed, poetic, and comprehensive work like the Shri Sai Satcharita, which was published over six years, provides the necessary substance for sustained community study, allowing devotees to fully immerse themselves in the Guru's life and teachings.
