Can you elaborate on the significance of the Uddhava Gita, also called Nath Bhagawat, as described in the provided text?

The text portrays the Uddhava Gita, or Nath Bhagawat, as a supremely important and divinely inspired book. Chapter 18 states that this dialogue between Krishna and Uddhava is considered even better than the famous Krishna-Arjuna dialogue in the Bharata. It is called the "loving speech of Nath," and the text claims that those who perform a reading of it with faith can attain God instantly, suggesting one does not even need to retreat to a forest for spiritual salvation. Its importance is further underscored by the fact that the merciful Sainath made sure it was read daily in Shirdi for the benefit of all devotees.
