The preface mentions that poetic books can be of different types. How is Shri Sai Satcharita classified, and why is this significant?

The source material from Chapter 0 explains that poetic books can be natural, graceful (Prasadik), or artificial. A book written solely on intelligence and scholarship might be good but lacks the eternal quality of divine inspiration. The Shri Sai Satcharita is explicitly identified as a 'grace-filled' or 'Prasad-janya' book. This is significant because it implies the work is not merely a product of human intellect but is imbued with Guru's grace. Without this divine gift, the text suggests a spiritual book will not leave a lasting impression on seekers or inspire faith. This grace-filled nature is why it is believed the book will be cherished and studied daily by devotees.
