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

According to the preface, detailed poetic biographies are considered most suitable for spiritual practices like study, recitation, Parayan, and Saptah. The primary reason given in Chapter 0 is that poetry is much easier to memorize than prose. A poetic composition stays in the memory and can be recalled when needed, a quality that was likely valued by ancient Sanskrit authors whose literature is mostly in verse. The text also notes that there is no established tradition of performing Parayans or Saptahs with prose biographies, making the poetic form the customary and superior choice for this type of devotional Guru service.
