How did Sai Baba's character reflect his spiritual attainments as a yogi?

Chapter 4 provides a deep insight into how Sai Baba's character was a direct reflection of his spiritual mastery. Described as the "Lord of Yoga," his primary ornament was peace. He was a "literal storehouse of knowledge" who had conquered the difficult-to-cross material world. This mastery is further explained by his detachment; he felt no joy or sorrow for worldly progress or decline and had no love for perishable things. His mind was perpetually "colored with the form of the Self," and his singular focus was the "attainment of the Supreme," showcasing a being who lived in a constant state of yogic absorption and non-duality.
