The relationship between the teacher and student is given a parting word, partially of warning. Krishna does not want these profound truths told to anyone who is not ready. Anyone lacking devotion or self-control, who does not want to hear spiritual instruction or who scoffs at it, should not be accepted as a student. The sacred act of giving spiritual instruction cannot be undertaken lightly. It is the highest work, and the man or woman who does it is most dear to Krishna.
