Why does the author advocate for writing Guru biographies in poetry rather than prose?

The author strongly prefers poetic biographies for several practical reasons related to devotional practice. According to Chapter 0, prose is difficult to memorize, whereas poetry is memorized quickly and easily. This is crucial because the text emphasizes the importance of performing regular study, recitations (Parayans), and weekly readings (Saptahs) of the biography. A poetic text stays in the memory and can be recalled when needed, making it far more suitable for these devotional practices. The author even notes this is likely why much of ancient Sanskrit literature is in verse, reinforcing that this is a time-tested method for performing Guru service through study.
