The preface quotes Dnyaneshwar Maharaj. Can you tell me what it says about other specific saints, like Kabir or Tukaram?

While the preface to the Shri Sai Satcharita, as detailed in Chapter 0, prominently features quotes from Lord Samarth Sadguru Dnyaneshwar Maharaj on the importance of Guru service, it does not mention other saints such as Kabir or Tukaram by name. The text does, however, make a general point about writing the biographies of many saints, describing it as a form of Guru service that yields spiritual fruits. However, the author qualifies this by stating that this service can be 'one-sided or partial' and may not be enough on its own to attain the ultimate spiritual goal. The focus remains on the principle of service rather than on providing a list of saints.
