Chapter 46 describes Sai Baba's actions as mysterious and hard to understand. Can you explain what this means based on the text?

The mysterious nature of Sai Baba's workings is a key theme in Chapter 46. The text explains that no one can truly understand his character because he 'plays all the games from within' yet flies the 'flag of detachment,' performing all actions while calling himself a non-doer. This paradox highlights his divine mystery. Furthermore, the chapter describes him as holding a 'subtle string,' pulling devotees near without letting himself be seen. He moves these strings in such a way that his methods remain unknown, yet his devotees ultimately feel his presence standing right behind them, guiding and protecting them in ways that are beyond ordinary comprehension.
