Can you explain the spiritual significance of the Nath Bhagawat and Jnaneshwari in the context of Sai Baba's teachings?

Within Sai Baba's circle, the Nath Bhagawat (the eleventh Skandha of the Bhagavat, also known as the Uddhava Gita) and the Jnaneshwari (also called Bhavartha Deepika) were held in the highest esteem. Chapter 18 describes the Nath Bhagawat as a divinely inspired book containing the 'loving speech of Nath,' and its dialogue between Krishna and Uddhava is considered even better than the Krishna-Arjuna dialogue in the Gita. Reading it with faith was believed to lead to the instant attainment of God. The Jnaneshwari, Jnandeva's commentary on the Gita, was also a cornerstone of the daily readings. Baba had these two books read daily in Shirdi, considering them a 'platform for the highest spiritual goal' and a means for the salvation of souls, thereby underscoring their profound spiritual importance in his teachings.
