What does the book say about performing Guru service in the digital age, for instance, by creating a podcast about a Sadguru?

The preface to the Shri Sai Satcharita was written before the advent of the digital age and therefore does not specifically mention modern forms of service like creating podcasts. However, the principles it outlines can be instructive. Chapter 0 discusses writing biographies as a key form of Guru service. It distinguishes between writing about worldly figures and the spiritually superior act of writing about saints or one's own Sadguru. The author emphasizes that for the purpose of study and recitation, detailed poetic biographies are most suitable because prose is harder to memorize and not traditionally used for devotional recitations.
