Why does the author advocate for writing spiritual biographies in poetry rather than prose, especially for practices like Parayans and Saptahs?

The author strongly prefers poetry for spiritual biographies intended for devotional practices. According to Chapter 0, detailed poetic biographies are considered most suitable for study, recitation, Parayan, or Saptah. The primary reason is that prose is difficult to memorize, while poetry is memorized quickly and easily, stays in the memory, and can be recalled when needed. The text notes that there is no tradition of performing Parayans or Saptahs of prose biographies, suggesting that the memorability and rhythmic nature of verse are essential for these devotional readings. This preference is also why much of the ancient Sanskrit literature is in verse.
