The Satcharitra mentions the importance of discipline. How is this concept illustrated in the text?

The concept of discipline is clearly illustrated in a story from Chapter 18. The narrator, having felt lazy, had skipped a portion of his daily reading of the Nath Bhagawat. Later, Sai Baba, knowing this, sent him on an errand to Shama's house. There, the narrator coincidentally found the book opened to the very section he had left incomplete. He understood this was Baba's way of enforcing discipline. As Chapter 18 concludes this particular anecdote, 'Discipline means regular reading.' This shows that Baba ensured his devotees maintained their spiritual practices consistently, even when they were inclined to neglect them.
