What does the source say about the tradition of Parayans and Saptahs, and can they be applied to texts other than biographies?

The practice of performing Parayans (readings) and Saptahs (weekly recitations) is described in Chapter 0 as a very ancient tradition that dates back to the Vedic era. These devotional readings are commonly performed for major Sanskrit works like the Vedas, Bhagavata, and Ramayana. The tradition also extends to revered Marathi works like Shri Dnyaneshwari. Importantly, Chapter 0 clarifies that these texts are often purely spiritual and worldly knowledge texts, not biographies. For devotees who consider the authors of these works, or the texts themselves, as their Guru, performing Parayans and Saptahs of them is considered the highest, incomparable, and salvation-granting form of Guru service.
