What is the recommended format for a Sadguru's biography for the purpose of devotional study, and what is the reasoning behind this recommendation?

For devotional practices like study, recitation (Parayan), or weekly readings (Saptah), the preface provides a specific recommendation. According to Chapter 0, while biographies can be written in prose or poetry, detailed poetic biographies are considered the most suitable. The text explains that there is no established tradition of performing Parayans or Saptahs of prose works. The primary reason provided for this preference is that prose is difficult to memorize. Therefore, poetic compositions are far more practical and effective for devotees to commit to memory and engage in regular, heartfelt recitation.
