Why are comprehensive biographies like the Shri Sai Satcharita considered more valuable for community practices like Saptahs than shorter accounts?

Comprehensive biographies are essential for community practices because they provide the necessary depth for sustained study and devotion. Chapter 0 points out that while some saints are mentioned in works by poets like Shri Dasganu Maharaj, these accounts are often just two or three pages long and are not detailed enough for a dedicated Parayan or Saptah. In contrast, a work like the Shri Sai Satcharita is a detailed, poetic, and comprehensive biography written specifically to be suitable for these devotional readings. This allows a community of devotees to fully immerse themselves in the Guru's life and teachings over an extended period.
