Why are some biographical works, like those by Shri Dasganu Maharaj, considered less suitable for a dedicated Parayan, and what makes a work like Shri Sai Satcharita more appropriate?

The source material draws a clear distinction regarding the suitability of different texts for a Parayan or Saptah. Chapter 0 explains that while one can perform a Parayan of Shri Dasganu Maharaj's larger works, they are not ideal if one wishes to focus on a single saint's biography. This is because the biographies within them are not comprehensive or detailed, often spanning only two or three pages. In contrast, a work like Shri Sai Satcharita is considered highly suitable because it is a detailed, poetic, and comprehensive biography dedicated entirely to one Guru, allowing devotees to fully immerse themselves in the saint's life.
