Why does the author advocate for poetic biographies over prose for spiritual study and recitation?

The author strongly favors poetic biographies for spiritual practices like study, recitation, Parayan (readings), and Saptah (weekly recitations). The rationale, as explained in Chapter 0, is primarily practical and traditional. The text notes that prose is difficult to memorize, whereas poetry is memorized quickly, stays in the memory, and is recalled easily when needed. This is suggested as the reason why ancient Sanskrit literature is mostly in verse. Furthermore, it is stated that there is no established tradition of performing Parayans or Saptahs of prose biographies, making detailed poetic biographies the most suitable format for these devotional acts of Guru service.
