From a writer's point of view, what are the spiritual merits of authoring a detailed biography of a saint like Sai Baba?

From the perspective of an author, creating a detailed biography of a saint is a significant form of spiritual service. Chapter 0 clarifies that a Sadguru takes service from devotees by having his biographies written. Therefore, the writer performs a direct Guru service through this act of creation. The spiritual benefits are magnified because when other devotees study and perform Parayans of the biography, the writer earns the merit of public service and of serving 'God in humanity (Jan-Janardan).' This act helps the entire congregation of devotees in their spiritual journey, allowing them to achieve the purpose of their lives through the work the author has provided.
