How does the practice of Parayan or Saptah contribute to serving the Guru and building a community of followers?

According to Chapter 0, studying and performing Parayans or Saptahs of a detailed poetic Guru biography is a significant form of Guru service. When a writer creates such a work and other devotees also study and perform these devotional readings, the writer earns the merit of serving both God in humanity (Jan-Janardan) and the public. Concurrently, the other devotees who participate in these readings are also guided toward achieving the purpose of their lives. This shared spiritual practice of engaging with the Guru's biography creates a strong bond and nurtures a community dedicated to the Sadguru's teachings.
