When Das Ganu presented his doubt about the Ishavasya Upanishad to Sai Baba, what was Baba's response as recorded in Chapter 20?

As detailed in Chapter 20 of the Sai Satcharitra, when Das Ganu went to Sai Baba in Shirdi with a doubt about the Ishavasya Upanishad, he received a surprising answer. Instead of explaining the scripture himself, Sai Baba told him, 'The resolution of this doubt of yours will be done by the maidservant at Kaka’s house When you return there.' This response highlights Baba's unique teaching methods, demonstrating that spiritual insight and the resolution of complex doubts can come from unexpected sources through the Guru's grace.
