Why was a new, detailed biography like the Shri Sai Satcharita necessary when other works about saints already existed?

The source material from Chapter 0 explains that while earlier works by poets like Shri Dasganu Maharaj mentioned saints, these biographies were not comprehensive or detailed, often spanning only two or three pages. This brevity made them unsuitable for dedicated Parayans or Saptahs, which are important community spiritual practices. To facilitate this deeper, collective form of study and devotion, a more substantial text was needed. The Shri Sai Satcharita was created to fill this gap, providing a detailed, sweet, and grace-filled biography specifically designed for Parayans, thereby giving the community a foundational text for shared worship.
