How does the practice of reciting a Guru's biography relate to the older traditions of spiritual study mentioned in the text?

The recitation of a Guru's biography is framed as a personalized extension of a very ancient spiritual tradition. As explained in Chapter 0, the practice of performing Parayans (devotional readings) and Saptahs (weekly recitations) dates back to the Vedic era and has been continuously applied to major works like the Vedas, Ramayana, and Shri Dnyaneshwari. The text notes that even though some of these are knowledge texts and not biographies, studying them is considered a high form of Guru service for those who revere the authors. Therefore, the study of a personal Sadguru's biography is presented as the most focused and intimate application of this time-honored practice, making it a direct and powerful act of devotion.
