But it's no use his trying to persuade his master that the little cuttlefish are spiders, for they are not the least like them. It's no use hiding things,--they are sure to come to light; and so it is with the heart,--its purposes will out. If the heart is enraged, the dark veins stand out on the forehead; if the heart is grieved, tears rise to the eyes; if the heart is joyous, dimples appear in the cheeks; if the heart is merry, the face smiles: thus it is that the face reflects the emotions of the heart. It is not because the eyes are filled with tears that the heart is sad; nor because the veins stand out on the forehead that the heart is enraged. It is the heart which leads the way in everything. All the important sensations of the heart are apparent in the outward appearance. In the "Great Learning" of Kôshi it is written, "The truth of what is within appears upon the surface." How then is the heart a thing which can be hidden? To answer when reproved, to hum tunes when scolded, show a diseased heart; and if this disease is not quickly taken in hand, it will become chronic, and the remedy become difficult: perhaps the disease may be so virulent that even Giba and Henjaku[99] in consultation could not effect a cure. So, before the disease has gained strength, I invite you to the study of the moral essays entitled _Shin-gaku_ (the Learning of the Heart). If you once arrive at the possession of your heart as it was originally by nature, what an admirable thing that will be! In that case your conscience will point out to you even the slightest wrong bias or selfishness. [Footnote 99: Two famous Indian and Chinese physicians.]
