Besides biographies, what other kinds of texts can be used for Parayans and Saptahs as a form of Guru service?

The practice of performing Parayans and Saptahs, which Chapter 0 describes as an ancient tradition, is not limited to Guru biographies. The text notes that these recitations are also commonly held for great Sanskrit works like the Vedas and Ramayana, as well as revered Marathi texts like Shri Dnyaneshwari and Shri Dasbodh. While these are classified as knowledge texts rather than biographies, Chapter 0 clarifies their role in Guru service. For those who consider the authors of these works, or even the texts themselves, as their Guru, the act of studying and reciting them is considered the highest, incomparable, and salvation-granting form of Guru service.
