Why are poetic biographies considered more suitable for spiritual study and recitation than prose biographies?

The preface in Chapter 0 argues that for spiritual practices like study, recitation, Parayan, or Saptah, detailed poetic biographies are the most suitable format. The primary reason provided is that poetry is memorized quickly and easily, stays in the memory, and is recalled in time. In contrast, prose is described as difficult to memorize. The text in Chapter 0 also notes there is no tradition of performing Parayans or Saptahs of prose biographies, suggesting this is a universal experience and custom. This preference for verse is even cited as the likely reason why ancient Sanskrit literature is mostly in poetic form.
