How does the act of writing and studying a Guru's biography serve a spiritual purpose for both the author and the readers?

As explained in the materials from Chapter 0, engaging with a detailed poetic Guru biography offers profound spiritual benefits. For the author, the act of writing the biography is considered a form of direct Guru service. Simultaneously, when other devotees study the work and perform Parayans, the author gains the additional merit of serving God within humanity (Jan-Janardan) and performing a public service. For the readers and devotees who study the text, this engagement helps them achieve the purpose of their own lives, creating a powerful cycle of shared spiritual merit and devotion.
