What personal feelings and motivations does the author express in Chapter 2 regarding the task of writing about Sai Baba?

As detailed in Chapter 2, the author felt a strong desire to collect Sai Baba's stories for the sake of simple and loving devotees. Despite this motivation, he was filled with self-doubt, noting he had crossed sixty years of age and felt his intellect was not sharp. He worried the effort might fail.

He believed that even if his effort only resulted in 'empty talk,' it should be for Sai’s love to achieve a spiritual goal.
