Why are comprehensive and detailed biographies like the Shri Sai Satcharita considered more suitable for community practices like Saptahs than other works?

Comprehensive biographies are preferred for community practices because they provide sufficient depth for sustained devotional reading. Chapter 0 notes that while some works by poets like Shri Dasganu Maharaj mention saints, the biographies within them are often not comprehensive, sometimes taking up only two or three pages, making them unsuitable for a Parayan or Saptah. In contrast, a detailed and poetic work like the Shri Sai Satcharita, written by Annasaheb Dabholkar, is specifically highlighted as being ideal for these devotional readings. Such detailed works allow a "congregation of devotees" to immerse themselves fully in the saint's life, fostering a powerful shared experience and building a stronger community.
