If I want to write a biography for spiritual purposes, what is the recommended format and how should I use the text afterwards?

Chapter 0 provides specific guidance on this. For the purpose of spiritual study and attaining salvation, detailed poetic biographies are considered most suitable. This is because there is a strong tradition of performing hundreds of readings (Parayans) and weekly recitations (Saptahs) of poetic works, which is not the case for prose. The text notes that prose is difficult to memorize, making poetic forms better for deep, repetitive study. This service should be undertaken with a firm resolve, pure heart, excellent faith, and selfless love, and you should encourage other devotees to do the same.
