Why are poetic biographies considered more suitable for devotional study than prose biographies?

Poetic biographies are considered more suitable for devotional practices like Parayans and Saptahs primarily because of memory and tradition. The preface explains in Chapter 0 that poetry is memorized quickly and easily, stays in the memory, and can be recalled in a timely manner. Prose, on the other hand, is described as difficult to memorize. This ease of recall is cited as a potential reason why much of ancient Sanskrit literature is in verse. Furthermore, Chapter 0 points out that there is no established tradition of performing devotional readings for prose biographies, making detailed poetic biographies the customary and preferred format for this type of Guru service.
