How does the format of a biography, like prose versus poetry, impact its use in spiritual practice?

The text strongly advocates for detailed poetic biographies over prose for spiritual practices like study, recitation (Parayan), or weekly recitations (Saptah). As explained in Chapter 0, the primary reason is that poetry is memorized quickly and easily, stays in the memory, and can be recalled when needed. In contrast, prose is considered difficult to memorize, and there is no established tradition of performing Parayans or Saptahs with prose biographies. The author suggests this is why ancient Sanskrit literature is mostly in verse, making poetic biographies the most suitable format for effective Guru service through study and recitation.
