Why are detailed Guru biographies considered important for devotional practices like Parayan?

Detailed Guru biographies are vital for devotional practices because they are comprehensive enough for a Parayan or Saptah (a continuous reading over several days). As explained in Chapter 0, some works, while valuable, may only contain brief, two-or-three-page biographies of saints, making them unsuitable for this focused purpose. By studying a detailed poetic Guru biography, the writer performs Guru service, and other devotees who study it also gain merit. This act of collective study allows both the writer and the readers to achieve the purpose of their lives and serve God in humanity.
