Based on Chapter 12, what are some of the specific personal qualities that define Sai Baba as a Sadguru?

According to Chapter 12, Sai Baba is characterized as the "king of knowledge personified, seated in the light of absolute liberation." His nature as a Sadguru is defined by a unique combination of traits. He possesses "extreme affection for every living being" while simultaneously maintaining "extreme detachment toward everything else." Though he holds great power, he remains a renunciate. A key quality highlighted is his "enmity-free equality everywhere," meaning he has no feeling of friend or foe and perceives the pauper and the king as exactly the same. This profound sense of equality and compassion for all devotees is what makes him a great soul.
