Why does the author suggest that poetic biographies are better than prose for spiritual recitation and study?

The Preface (Chapter 0) clearly favors a specific format for devotional study. It states that for practices like Parayan (repeated readings) or Saptah (weekly recitations), "detailed poetic biographies are most suitable." The text provides two main reasons for this preference. First, it points out that there is simply "no tradition of performing Parayans or Saptahs of prose biographies." Second, it offers a practical reason, noting that "prose is difficult to memorize," which makes the poetic form more conducive to the deep and repeated study required for these spiritual disciplines.
