Why does the author advocate for composing spiritual biographies in poetry rather than prose?

The author strongly prefers poetry for spiritual biographies intended for study, recitation, Parayan, or Saptah. The reasoning provided in Chapter 0 is primarily practical: poetry is much easier to memorize and stays in the memory more effectively than prose. This ensures the teachings can be recalled when needed. The author supports this by pointing out that much of ancient Sanskrit literature is in verse for this very reason. Furthermore, a tradition exists for performing Parayans and Saptahs of poetic works, a practice not typically applied to prose biographies, making poetry the more suitable format for these devotional activities.
