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

Comprehensive and detailed biographies are essential for community practices because they provide sufficient substance for prolonged devotional study. Chapter 0 notes that while some works, like those by Shri Dasganu Maharaj, mention saints, they are not detailed enough for a Parayan of a single saint's life, often spanning only two or three pages. In contrast, a detailed, poetic, and comprehensive work like the 'Shri Sai Satcharita' is perfectly suited for Parayans and Saptahs. This allows the congregation of devotees to deeply immerse themselves in the Guru's life and teachings over an extended period, which is a powerful form of collective service and community formation.
