What is the primary topic introduced at the beginning of Chapter 24 of the Sai Satcharitra?

Chapter 24 begins by fulfilling a promise made in the previous chapter to narrate how Sainath Guru, described as a 'cloud of mercy,' imparts teachings even through humor and jokes. The chapter emphasizes that worshipping Maharaja Sai helps one achieve both worldly interests and the supreme spiritual goal, or Parmartha. As detailed in Chapter 24, meditation on one's true self is said to bring contentment to the heart, and listening to these stories leads to internal peace and salvation, destroying the fear of worldly existence.
