Why does the preface suggest that poetic biographies are more suitable for Guru service than prose?

The preface in Chapter 0 argues that poetry is superior to prose for sacred biographies because it is quickly and easily memorized. Unlike prose, which can be difficult to commit to memory, poetry stays in the mind and can be recalled when needed. This is presented as a primary reason why ancient Sanskrit literature is predominantly in verse. Therefore, the study, recitation, Parayan, and Saptah of a detailed poetic Guru biography is described as the best way to perform Guru service, making the spiritual practice more effective and accessible for the devotee.
