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

The author of the preface, as detailed in Chapter 0, strongly advocates for detailed poetic biographies as the most suitable format for spiritual practices like study, Parayan, and Saptah. The primary reason given is that poetry is much easier to memorize and stays in the memory for longer periods, allowing it to be recalled when needed. Prose, on the other hand, is described as difficult to memorize. The author supports this by pointing out that much of the ancient Sanskrit literature is in verse, suggesting this was a deliberate choice for easier retention and transmission of knowledge. This makes poetic works the ideal medium for the Guru service of recitation.
