How does the text describe the significance of the Uddhava Gita, and who was instructed to read it?

Chapter 18 elevates the Uddhava Gita, described as a part of the Nath Bhagawat, to a position of profound importance. The text calls it a "very divinely inspired book" and makes a remarkable comparison, stating that the dialogue between Krishna and Uddhava within it is even better than the famous dialogue between Krishna and Arjuna in the Bharata. It is presented as a direct path to spiritual attainment, with the text claiming that those who read it with faith can attain God instantly without needing to retreat to a forest. Sai Baba specifically ordered his devoted disciple Dixit to undertake the reading of this book for the purpose of the "salvation of souls."
