How does the story about Das Ganu in Chapter 20 connect to what was told in the previous chapter?

Chapter 20 explicitly creates a link to the narrative from the previous chapter. It begins the story of Das Ganu by reminding the reader that at the end of the prior chapter, it was mentioned that Baba would explain the meaning of a Shruti (scripture) through a maidservant. Chapter 20 then identifies this as the "current connection of the story" and proceeds to detail the context: Das Ganu had a doubt while writing his commentary on the Ishavasya Upanishad, and Baba's perplexing instruction to seek the answer from a maidservant is the event that was foreshadowed.
