Based on the preface, why might a devotee choose to read Shri Sai Satcharita for a Saptah over the works of Shri Dasganu Maharaj?

A devotee might prefer Shri Sai Satcharita for a Saptah due to its comprehensive and detailed nature. While Chapter 0 praises Shri Dasganu Maharaj's two biographies of Baba as excellent and graceful, it explicitly states they are 'very short.' For a devotee wishing to perform a Parayan or Saptah specifically on a single saint's life, a brief account taking up only a few pages is considered less useful than a comprehensive work. The Shri Sai Satcharita, in contrast, is presented as a detailed and complete biography, making it more suitable for such an immersive and extended study.
