Why are poetic biographies preferred over prose for spiritual study and recitation according to the text?

The text strongly recommends detailed poetic biographies for spiritual practices like study, Parayan, or Saptah. The reasoning provided in Chapter 0 is primarily practical and traditional. Prose is described as being difficult to memorize, whereas poetry is learned quickly, stays in the memory, and can be recalled easily when needed. The author suggests this is why ancient Sanskrit literature is mostly in verse. Furthermore, it's mentioned that there is no established tradition for performing Parayans or Saptahs of prose biographies, making poetic works the customary and more suitable format for this type of devotional Guru service.
