What was Baba's fundamental advice for living a happy life, and how does it connect to the concept of Brahman?

Sai Baba's constant advice to his devotees was, "Do not worry in the least; always be full of joy; do not worry until death." This guidance is directly linked to a core spiritual principle. As Chapter 17 explains, this teaching is a practical translation of the famous Taittiriya Shruti, "Brahman is bliss." The text encourages one to discard all ignorance of happiness or sorrow and acquire special knowledge, known as Vijnana, because the knowledge of Brahman is always near. By embracing joy and not worrying, one aligns with the blissful nature of the ultimate reality, which was the direction of Baba's teachings.
