What is the dual benefit of writing and studying a detailed biography of a Guru like Sai Baba for the community?

According to the insights from Chapter 0, there is a significant dual benefit. Firstly, for the writer, creating a detailed poetic Guru biography is a form of direct Guru service. Secondly, and crucial for the community, is that when other devotees study and perform Parayans of the work, the writer gains the merit of serving God within humanity (Jan-Janardan) and public service. Simultaneously, the devotees who participate in these studies and Parayans are also able to achieve the purpose of their lives, creating a mutually beneficial spiritual ecosystem that strengthens the entire community.
