What is the historical basis for the practice of Parayans and Saptahs as mentioned in the text?

The text establishes a long and revered history for the devotional practices of Parayan (repeated readings) and Saptah (weekly recitations). According to Chapter 0, this tradition is not new but is very ancient, with roots going back to the Vedic era. The author notes that Parayans and Saptahs of great Sanskrit works such as the Vedas, Bhagavata, Ramayana, and Yoga Vasistha are still performed daily. This tradition also includes world-revered Marathi works like Shri Dnyaneshwari and Shri Dasbodh, demonstrating the deep cultural and spiritual significance of these devotional reading practices.
