How did Das Ganu approach Sai Baba in Shirdi, and what was the nature of their conversation about his work on the Upanishad?

As recounted in Chapter 20, Das Ganu approached Sai Baba with great reverence. Upon arriving in Shirdi, he went for Sai's darshan, placed his head on Baba's feet, and bowed prostrate in happiness. Their conversation was familiar and insightful. Baba asked about his well-being, and Ganu replied that with Baba's grace, he had no reason to be sad. He then directly addressed the challenge he was facing with his writing, telling Baba, "You yourself made me start it, and as it took shape you hit such a snag in the middle that no one can unravel it." This conversation took place while Das Ganu was massaging Baba's feet, highlighting the intimate and service-oriented relationship between the devotee and his Guru.
