What historical context is provided for the practices of 'Parayans' and 'Saptahs'?

The preface in Chapter 0 explains that the practice of performing Parayans (readings) and Saptahs (weekly recitations) is not new but is, in fact, very ancient, with roots dating back to the Vedic era. To illustrate this long-standing tradition, the text mentions that these devotional readings happen daily for great Sanskrit works such as the Vedas, Bhagavata, Ramayana, and Yoga Vasistha. The tradition also extends to revered Marathi works like Shri Dnyaneshwari, Shri Nath Bhagavata, and Shri Dasbodh, demonstrating the deep historical and cultural significance of these practices in spiritual life.
