According to the text, what is the significance of the Nath Bhagawat, and how did it feature in Baba's lesson about laziness?

The Nath Bhagawat is described as a sacred text saturated with the sentiment of Guru-devotion, read daily by devoted individuals like Dixit. Chapter 18 provides its esteemed lineage, tracing the wisdom from Narayan to Brahma, Narada, Vyasa, and eventually to Eknath, who served it as a "banquet of juicy delicacies." This revered book became the central element in Sai Baba's lesson about laziness. When a devotee neglected his morning reading of this very text, Baba orchestrated events to ensure he completed it. By having the devotee find the book at Shama's house, opened to the exact unfinished portion, Baba underscored the importance of this scripture and the non-negotiable discipline of its regular study.
