Why are poetic biographies preferred over prose for spiritual practices like Parayans and Saptahs?

Poetic biographies are considered most suitable for study, recitation, Parayan, or Saptah for several key reasons. According to Chapter 0, prose is difficult to memorize, whereas poetry is learned quickly, stays in the memory, and is recalled more easily when needed. The text notes that this is likely why much of the ancient Sanskrit literature is in verse. Furthermore, it is mentioned that there is no established tradition of performing Parayans or Saptahs of prose biographies, making the study of poetic and detailed Guru biographies the best and most customary way to perform this type of Guru service.
