How does the Dnyaneshwari's view on serving saints, as cited in the preface, compare to the teachings in Buddhist scriptures?

The provided text from the preface of the Shri Sai Satcharita does not draw a comparison between the teachings of the Dnyaneshwari and Buddhist scriptures. Instead, as explained in Chapter 0, the preface quotes Lord Samarth Sadguru Dnyaneshwar Maharaj to illustrate the ancient principle of Guru service, which has existed since Vedic times. It emphasizes that to gain knowledge, one must serve the saints with their entire being—body, mind, and soul—and without ego. The preface highlights that this selfless service is the doorway to understanding and will enlighten the heart, leaving no room for doubt.
