How did Sai Baba's grace specifically help Das Ganu with his translation project, and what does this reveal about the Guru-disciple relationship?

Das Ganu, who had little knowledge of the Sanskrit language, undertook the immense task of translating the Ishavasya Upanishad into Prakrit verses. As described in Chapter 20, he found this task incredibly challenging because he couldn't grasp the text's inner meaning. However, the narrative states that 'when Sainath showed grace, its difficulty vanished.' This divine assistance enabled him to complete his verse-commentary, which was then accepted by learned individuals. The author poetically describes this by saying, 'Ganudas's speech is like a stream of milk; Sai's grace is the sugar in it.' This illustrates a key aspect of the Guru-disciple relationship: the Guru's grace can overcome a disciple's limitations, making seemingly impossible tasks achievable and illuminating the path to profound understanding.
