How did Sai Baba's use of humor and spontaneity contrast with the patience required from his devotees?

Sai Baba's methods presented a fascinating duality. On one hand, as Chapter 27 describes, devotees needed immense patience, especially when they brought books for his blessing only to see him give them to someone else. This taught them to wait for his grace on his terms. On the other hand, the text also reveals a completely different side to his grace. It mentions that once it came to his mind, 'when it was not in anyone's thought, through casual joking and humor, he would fulfill the devotee's purpose.' This spontaneity shows that while patience was a virtue he cultivated in his followers, his grace was not bound by any single method and could manifest suddenly and joyfully, reminding devotees that his ways were ultimately surprising and beyond their full comprehension.
