What are Parayans and Saptahs, and what is their historical context according to the preface?

The preface describes Parayans as the practice of performing hundreds of readings of a text, while Saptahs are weekly recitations. These are to be done with a firm resolve, pure heart, and selfless love. As mentioned in Chapter 0, these devotional practices are a key component of Guru service, especially when applied to a Sadguru's biography. The text emphasizes that this tradition is very ancient, with its roots dating back to the Vedic era. It is a common and ongoing practice for great Sanskrit works like the Vedas and Ramayana, as well as for revered Marathi texts, demonstrating its long-standing importance in spiritual study.
