What was Sai Baba's cryptic instruction to Das Ganu regarding his doubt about the Ishavasya Upanishad?

When Das Ganu, feeling stuck in his attempt to write a commentary on the Ishavasya Upanishad, brought a specific doubt to Sai Baba, he did not receive a direct scholarly answer. Instead, as Chapter 20 recounts, Baba gave him a cryptic instruction. 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 puzzling response showcases Baba's unconventional teaching methods, suggesting that the answer to a profound spiritual question would be revealed through an unexpected and humble source.
