What was Sai Baba's peculiar instruction to Das Ganu for resolving his doubt about the Ishavasya Upanishad?

When Das Ganu approached Sai Baba in Shirdi with his profound doubt about the meaning of the Ishavasya Upanishad, he received a very surprising and unconventional instruction. As detailed in Chapter 20, instead of providing a direct explanation himself, Baba told Das Ganu that the solution to his problem would come from an unexpected source. Baba's exact words were: "The resolution of this doubt of yours will be done by the maidservant at Kaka’s house When you return there." This illustrates Baba's unique and often indirect method of teaching, using ordinary people and situations to impart profound spiritual wisdom.
