How does the text contextualize the practice of Parayans and Saptahs, and can this practice be applied to texts other than biographies?

The text establishes Parayans (readings) and Saptahs (weekly recitations) as a very ancient tradition dating back to the Vedic era. Chapter 0 explains that this practice is central to deriving spiritual benefit from a Sadguru's biography. However, the practice is not limited to biographies. The author notes that Parayans and Saptahs of great Sanskrit works like the Vedas, Bhagavata, and Ramayana are common. Similarly, revered Marathi works such as Shri Dnyaneshwari and Shri Dasbodh are also used for daily recitations. The text points out that these latter examples are not biographies but are purely knowledge texts, demonstrating the broad application of this devotional practice.
