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

The text strongly advocates for detailed poetic biographies over prose for spiritual practices like study, recitation, Parayan, and Saptah. As detailed in Chapter 0, the primary reason is that poetry is much easier to memorize and recall than prose. This ease of memorization ensures the teachings remain in the devotee's memory and can be recalled when needed. The preface supports this by pointing out that ancient Sanskrit literature is predominantly in verse for this very reason. It also notes that there is no established tradition of performing Parayans or Saptahs of prose biographies, making poetic works the customary and more suitable choice for this type of Guru service.
