Why was the Uddhava Gita considered such a special book in Baba's circle?

The Uddhava Gita, also referred to as Nath Bhagawat in Chapter 18, is described as a "very divinely inspired book." Its significance is highlighted through several points. It is said that its sweetness caused the God-devoted Tukaram to perform a thousand readings in solitude. The text explicitly states that those who perform the reading with faith can attain God instantly. Furthermore, the dialogue between Krishna and Uddhava is praised as being even better than the famous dialogue between Krishna and Arjuna in the Bharata. It is ultimately presented as the loving speech of Nath (the Lord) and a platform for achieving the highest spiritual goal, which is why the merciful Sainath had it read daily.
