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

Chapter 24 introduces the unique and extraordinary way in which Sai Baba imparts profound teachings through humor and jokes. The chapter opens with a promise to narrate how Sainath Guru, described as a 'cloud of mercy,' uses this method. As detailed in the text of Chapter 24, people eagerly awaited Baba's humor, which was delivered with a smiling face and playful eyes. This approach was not for mere amusement; its purpose was to impress the essence of truth upon his devotees in a way that was beneficial for achieving both worldly interests and the supreme spiritual goal, known as Parmartha.
