What does the text reveal about the history and purpose of the practices known as Parayans and Saptahs?

The text provides significant context for the practices of Parayans (readings) and Saptahs (weekly recitations). According to Chapter 0, these devotional practices are very ancient, with roots tracing back to the Vedic era. The author notes that it is common to see and hear of Parayans and Saptahs being performed daily for major Sanskrit works like the Vedas, Bhagavata, and Ramayana, as well as for revered Marathi texts such as Shri Dnyaneshwari. Their purpose is to facilitate deep study and immersion in a sacred text. The author specifically recommends applying this ancient tradition to detailed, poetic Guru biographies as the most effective way to perform Guru service, noting that there is no tradition of performing these recitations for prose biographies.
