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

The text argues that for spiritual practices like study, recitation, Parayan, or Saptah, detailed poetic biographies are the most suitable format. Chapter 0 explains that there is no established tradition of performing such recitations with prose biographies. The primary reason given is that prose is difficult to memorize. Poetry, on the other hand, is memorized quickly and easily, stays in the memory, and can be recalled when needed. The text points to the fact that ancient Sanskrit literature is mostly in verse as evidence supporting this preference.
