When Das Ganu presented his doubt about the Ishavasya Upanishad to Sai Baba, what was Baba's surprising instruction to him as detailed in Chapter 20?

After Das Ganu arrived in Shirdi troubled by his inability to understand the deeper meaning of the Upanishad he was translating, he presented his doubt to Sai Baba. As Chapter 20 recounts, Baba's response was quite unexpected. Instead of providing a direct philosophical 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 puzzling instruction redirected Das Ganu from the great Satguru to a seemingly humble and ordinary person, setting the stage for a lesson on how wisdom can be found in unexpected places.
