Are all biographies of saints suitable for devotional group readings like a Parayan?

The preface discussed in Chapter 0 suggests that not all biographies are equally effective for devotional practices like Parayans or Saptahs. It is noted that while works like Shri Dasganu Maharaj's Shri Bhaktalilamrut are valuable, the biographies of individual saints within them are often too brief, spanning only two or three pages, making them unsuitable for a focused Parayan. For such a dedicated practice, a comprehensive, detailed, and poetic biography is required. The text specifically elevates the Shri Sai Satcharita by Annasaheb Dabholkar as the ideal work for this purpose due to its detailed and inspirational nature.
