How does Sai Baba interact with people who come to see him? Is he affected by their attitudes or whether they give him offerings?

The source material in Chapter 35 portrays Sai Baba as being completely beyond duality and detached from the actions of his devotees. It explicitly states that he feels no joy in being worshipped nor sorrow in being insulted, existing in a state free from joy or grief. Whether someone bows to him or not, or gives Dakshina or not, Sai, described as a 'cloud of mercy,' does not disregard anyone. Despite this outward detachment, as Chapter 35 explains, he has a wonderful power to attach a devotee's devotion to his feet, regardless of their initial intent, which is a marvelous aspect of his nature.
