Why are detailed works like the Shri Sai Satcharita considered more suitable for devotional reading compared to other biographical accounts?

Detailed works like the Shri Sai Satcharita are considered more suitable for devotional readings, known as Parayans or Saptahs, primarily because of their comprehensive nature. Chapter 0 notes that some earlier works, such as those by Shri Dasganu Maharaj, were not ideal for this purpose because a specific saint's biography might only span two or three pages, making a dedicated, immersive reading difficult. In contrast, the preface highlights that the Shri Sai Satcharita is a detailed, poetic, and comprehensive work, making it perfectly suited for the sustained study and devotion involved in a Parayan, similar to the well-known Guru Charitra.
