Why is writing a detailed biography of a Guru considered a significant form of service with dual benefits?

Writing a detailed poetic biography of a Guru is a profound act of service because it benefits both the writer and the community. According to Chapter 0, the author performs Guru service through the act of writing itself. Simultaneously, when other devotees study and perform Parayans of the completed work, the writer accrues the merit of serving God in humanity (Jan-Janardan) and performing public service. This enables other devotees to also achieve their life's purpose, making the creative act a service to both the Guru and fellow seekers.
