What did Sai Baba declare as the purpose behind having his life story (Charitra) written and shared?

In Chapter 3, Sai Baba explains that the purpose of documenting his life story is twofold: the welfare of his devotees and the fulfillment of his own avataric mission. He explicitly states, "In this alone is your welfare, and also the fulfillment of my avatar." The goal was to create a spiritual tool for his followers. He assured the author that by writing this divine play, ignorance would be destroyed. For those who listen with devotion, he promised that their consciousness of worldly affairs would fade, replaced by rising waves of love and devotion, leading them to attain natural joy, eternal happiness, and peace.
