Why were earlier poetic works by authors like Shri Dasganu Maharaj considered less suitable for a dedicated Parayan of a single saint when compared to a work like the Shri Sai Satcharita?

The preface in Chapter 0 clarifies this distinction based on comprehensiveness. While one can perform a Parayan of the works by Shri Dasganu Maharaj, they are not ideal if the goal is to study a single saint's biography in detail. The text states that the biographies of individual saints within these works are not comprehensive, often spanning only two or three pages. In contrast, the Shri Sai Satcharita is presented as a 'detailed, poetic, comprehensive, and famous' work written specifically about Sai Baba. This level of detail makes it uniquely suitable for an immersive Parayan or Saptah focused solely on him, an attribute the earlier, broader collections lack.
