What was Sai Baba's unusual instruction to Das Ganu regarding his doubt about the Upanishad, and what might this imply?

In Chapter 20, when Das Ganu presented his profound doubt about translating the Ishavasya Upanishad, Sai Baba gave him a very unusual instruction. Instead of offering a scholarly explanation, 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 surprising response, which is a key part of the narrative, implies that spiritual wisdom and the resolution of complex doubts can come from unexpected and humble sources. It demonstrates Baba's unique teaching method, which often went beyond conventional wisdom to impart deeper lessons.
