Why are detailed poetic biographies preferred over prose for spiritual study and recitation?

Detailed poetic biographies are considered most suitable for spiritual practices like study, Parayan, or Saptah for several key reasons. According to Chapter 0, poetry is memorized much more quickly and easily than prose. It also stays in the memory and can be recalled in time, which is crucial for devotional recitation. The text notes that this is likely why ancient Sanskrit literature is mostly in verse. Furthermore, it's mentioned that there is no established tradition of performing Parayans or Saptahs for prose biographies, making poetic works the customary and superior choice for this form of Guru service.
