What is the primary purpose and introduction of Chapter 36 as described in the text?

The introduction to Chapter 36 serves to set a devotional tone and explain the purpose of the stories that follow. It begins with traditional invocations and a promise to tell another 'succulent story' to quench the spiritual thirst of the listener. The text explicitly states that if a fortunate soul desires spiritual welfare, they should listen respectfully to Sai's stories. According to Chapter 36, the narration of the 'Sai Charitra' is intended to purify the ears of the listeners and the mouths of the speakers everywhere. It then transitions from this philosophical introduction to begin the story of two gentlemen from Goa who came for Sai's darshan.
