His disciples are to the teacher as all the objects of heaven and earth are to the sun. Some are responsive to the light of the sun, and become hot or cold. Some grow and thrive, and bring out their color and fragrance. Some close their eyes or become blind in the light of the sun. Some begin their life's activities as the sun rises; and some await the rising of the sun during the dark, depressing night in pain and suffering. Some look forward to the clearing of the clouds and the smiles of the sun. But the stars and planets in heaven are still more responsive and more closely connected with the special current of the sun; and so are the disciples who are close to the spirit of the teacher. They are his special apostles; they give out the light of the sun that is reflected in their heart.
