Can you explain the concept of 'Parayan' and its benefits as discussed in the context of Guru biographies?

A 'Parayan' or 'Saptah' refers to the devotional reading of a sacred text, often over a set period. According to the insights from Chapter 0, performing a Parayan of a detailed poetic Guru biography is a form of service to the Guru. For the writer of such a biography, it is a direct act of Guru service. When other devotees also study and perform Parayans of the work, the writer gains the additional merit of serving God in humanity (Jan-Janardan) and performing public service. Furthermore, this practice helps the devotees who participate in the reading to achieve the ultimate purpose of their lives.
