What surprising instructions did Sai Baba give to Das Ganu to resolve his confusion about the Ishavasya Upanishad?

When Das Ganu approached Sai Baba in Shirdi with his doubt about the deep meaning of the Ishavasya Upanishad, Baba's response was highly unconventional. Instead of providing a direct philosophical explanation, Baba gave him a puzzling instruction. As detailed in Chapter 20, 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 unexpected guidance demonstrates Baba's unique method of teaching, often using ordinary people and situations to impart profound spiritual wisdom, rather than engaging in direct scriptural discourse.
