How can a person obtain spiritual knowledge from saints, based on the teachings of Dnyaneshwar Maharaj?

Drawing from Dnyaneshwar Maharaj's commentary, Chapter 0 outlines a clear process for acquiring spiritual knowledge. The fundamental step is to "serve the saints with your entire being," as service is described as the very doorway to the treasure of knowledge. To do this correctly, one must surrender at their feet with body, mind, and soul, and perform all service without any ego. The text promises that when this selfless service is rendered, the saints will then impart the knowledge that enlightens the heart and completely removes any doubts that may arise.
