Why are detailed poetic biographies preferred over prose for study and recitation, such as Parayans and Saptahs?

Detailed poetic biographies are considered most suitable for spiritual practices like study, recitation, Parayan, or Saptah primarily because of memory and tradition. Chapter 0 explains that poetry is memorized quickly and easily, stays in the memory, and can be recalled when needed. In contrast, prose is difficult to memorize. This preference is supported by historical precedent, as the text notes that ancient Sanskrit literature is mostly in verse for this very reason. Furthermore, Chapter 0 states there is no established tradition of performing Parayans or Saptahs of prose biographies, making poetic works the standard for this form of Guru service.
