Based on Chapter 46, what defines 'supreme peace' and how did Baba exemplify this quality in the face of criticism?

According to the teachings in Chapter 46, the sign of supreme peace is an extraordinary and unwavering steadiness, even when faced with circumstances that might provoke anger. Sai Baba exemplified this quality perfectly when his followers condemned his financial decision. The text states his steadiness did not waver even an atom's worth, which is the hallmark of supreme peace. This is because He was an experiencer of this state, who saw God in all beings and was completely devoid of anger. The source explains that for those who are firm in the vision of discrimination, anger does not come forward, and even if an occasion for it arises, their storehouse of peace opens.
