What does Dnyaneshwar Maharaj teach about the path to acquiring knowledge from saints?

The preface in Chapter 0 references Lord Samarth Sadguru Dnyaneshwar Maharaj's commentary on the Shrimad Bhagavad Gita to explain how to gain knowledge. His teachings state that if you wish to attain knowledge, you must serve the saints with your entire being—body, mind, and soul. He describes service as the very doorway to the treasure of knowledge. This service must be performed without ego. When this is done, the saints will impart the requested knowledge, which enlightens the heart and resolves all doubts, as detailed in the quoted verses from Shri Dnyaneshwari.
