Today: “The criminals must be prosecuted swiftly and completely.  Then, order and union can be restored.” – from the I Ching

#21, line 6, #24

Since the hexagram is made up of the trigrams for thunder and for lightning, it indicates how obstacles are forcibly removed in nature. Energetic biting through overcomes the obstacle that prevents joining of the lips; the storm with its thunder and lightning overcomes the disturbing tension in nature. Recourse to law and penalties overcomes the disturbances of harmonious social life caused by criminals and slanderers.

BITING THROUGH has success.
It is favorable to let justice be administered.

When an obstacle to union arises, energetic biting through brings success. This is true in all situations. Whenever unity cannot be established, the obstruction is due to a talebearer and traitor who is interfering and blocking the way. To prevent permanent injury, vigorous measures must be taken at once. Deliberate obstruction of this sort does not vanish of its own accord. Judgement and punishment are required to deter or obviate it.
However, it is important to proceed in the right way. The hexagram combines Li, clarity, and Chên, excitement. Li is yielding, Chên is hard. Unqualified hardness and excitement would be too violent in meting out punishment; unqualified clarity and gentleness would be too weak. The two together create the just measure. It is of moment that the man who makes the decisions (represented by the fifth line) is gentle by nature, while he commands respect by his conduct in his position. Thunder and lightning:
The image of BITING THROUGH.
Thus the kings of former times made firm the laws
Through clearly defined penalties.

Penalties are the individual applications of the law. The laws specify the penalties. Clarity prevails when mild and severe penalties are clearly differentiated, according to the nature of the crimes. This is symbolized by the clarity of lightning. The law is strengthened by a just application of penalties. This is symbolized by the terror of thunder. This clarity and severity have the effect of instilling respect; it is not that the penalties are ends in themselves. The obstructions in the social life of man increase when there is lack of clarity in the penal codes and slackness in executing them. The only way to strengthen the law is to make it clear and to make penalties certain and swift.

Nine at the top means:
His neck is fastened in the wooden cangue,
So that his ears disappear.
Misfortune.

In contrast to the first line, this line refers to a man who’s incorrigible. His punishment is the wooden cangue, and his ears disappear under it—that is to say, he is deaf to warnings. This obstinacy leads to misfortune.¹

RETURN. Success.
Going out and coming in without error.
Friends come without blame.
To and fro goes the way.
On the seventh day comes return.
It furthers one to have somewhere to go.

After a time of decay comes the turning point. The powerful light that has been banished returns. There is movement, but it is not brought about by force. The upper trigram Kun is characterised by devotion; thus the movement is natural, arising spontaneously. For this reason the transformation of the old becomes easy. The old is discarded and the new is introduced. Both measures accord with the time; therefore no harm results. Societies of people sharing the same views are formed. But since these groups come together in full public knowledge and are in harmony with the time, all selfish separatist tendencies are excluded, and no mistake is made. The idea of RETURN is based on the course of nature. The movement is cyclic, and the course completes itself. Therefore it is not necessary to hasten anything artificially. Everything comes of itself at the appointed time. This is the meaning of heaven and earth.
All movements are accomplished in six stages, and the seventh brings return. Thus the winter solstice, with which the decline of the year begins, comes in the seventh month after the summer solstice; so too sunrise comes in the seventh double hour after sunset. Therefore seven is the number of the young light, and it arises when six, the number of the great darkness, is increased by one. In this way the state of rest gives place to movement.

Thunder within the earth:
The image of THE TURNING POINT.
Thus the kings of antiquity closed the passes
At the time of solstice.
Merchants and strangers did not go about,
And the ruler
Did not travel through the provinces.

The winter solstice has always been celebrated in China as the resting time of the year – a custom that survives in the time of rest observed at the new year. In winter the life energy, symbolised by thunder, the Arousing, is still underground. Movement is just at its beginning; therefore it must be strengthened by rest so that it will not be dissipated by being used prematurely. This principle, i.e., of allowing energy that is renewing itself to be reinforced by rest, applies to all similar situations. The return of health after illness, the return of understanding after an estrangement: everything must be treated tenderly and with care at the beginning, so that the return may lead to a flowering.

1. It should be noted here that there is an alternative interpretation of this hexagram, based on the idea, “Above, light (the sun); below, movement.” In this interpretation the hexagram symbolizes a market below, full of movement, while the sun is shining in the sky above. The allusion to meat suggests that it is a food market. Gold and arrows are the articles of trade. The disappearance of the nose means the vanishing of smell, that is, the person in question is not covetous. The idea of poison points to the dangers of wealth, and so on throughout.
Confucius says in regard to the nine at the beginning in this hexagram: “The inferior man is not ashamed of unkindness and does not shrink from injustice. If no advantage beckons he makes no effort. If he is not intimidated he does not improve himself, but if he is made to behave correctly in small matters he is careful in large ones. This is fortunate for the inferior man.”
On the subject of the nine at the top Confucius says: “If good does not accumulate, it is not enough to make a name for a man. If evil does not accumulate, it is not strong enough to destroy a man. Therefore the inferior man thinks to himself, ‘Goodness in small things has no value, ‘ and so neglects it. He thinks, ‘Small sins do not harm,’ and so does not give them up. Thus his sins accumulate until they can no longer be covered up, and his guilt becomes so great that it can no longer be wiped out.”
