What is the main purpose of narrating Sai's life story, according to the introduction in Chapter 36?

According to the introduction in Chapter 36 of the Shri Sai Satcharitra, the primary purpose of narrating Sai's stories is the spiritual upliftment of the listener. The text describes these stories as 'the very water of self-bliss,' which, when consumed, 'removes the fatigue and misery of worldly existence, and a state of happiness is attained.' It is presented as a path for a 'fortunate soul' to achieve their 'own spiritual welfare.' Furthermore, Chapter 36 reveals that Sai himself 'loves his own stories very much' and uses them as a means to provide for his devotees, protect them completely, and fulfill their desires, thus redeeming 'infinite beings.'
