In Homer’s Odyssey Mentor was a close friend of Odysseus, the wisest of the Greeks, whom Odysseus made the teacher and guardian of his son Telemachus, while Odysseus was waging war at Troy. I recommend that you make a study of the wisdom of one of the famous persons listed in Column 3 of Kokoro, or one of the Great Traditions, and keep a log of the discoveries you make following their wise guidance. In addition to its practical applications, Column 3 is a journey through time of the collective legacy of a good part of humanity.
