Why does the author prefer poetic biographies over prose for the purpose of Guru service?

The author strongly advocates for detailed poetic biographies as the most suitable format for Guru service, particularly for study, recitation, and weekly readings (Saptahs). As explained in Chapter 0, the primary reason is practical: poetry is memorized quickly and easily, remains in one's memory, and can be recalled when needed. Prose, on the other hand, is difficult to memorize. The text notes that there is no established tradition of performing Parayans or Saptahs of prose biographies. The author even suggests that the prevalence of verse in ancient Sanskrit literature is likely due to this very advantage of memorability, making poetic biographies the ideal medium for devotional study.
