51 (Shock, Thunder) -
This movement is so violent that it arouses terror. It is symbolized by thunder, which bursts forth from the earth and by its shock causes fear and trembling.
The shock terrifies for a hundred miles, And he does not let fall the sacrificial spoon and chalice.
Movement within the mind depends for its success partly on circumstances. If there is neither a resistance that might be vigorously combated, nor a yielding that permits of victory - if, instead, everything is tough and inert like mire - movement is crippled.
-- 24 (The Turning Point) -
On the seventh day comes return.
After a time of decay comes the turning point. The powerful light that has been banished returns. It is not necessary to hasten anything artificially. Everything comes of itself at the appointed time. 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.
Walking in the midst of others, one returns alone.
A man is in a society composed of inferior people, but is connected spiritually with a strong and good friend, and this makes him turn back alone. Although nothing is said of reward and punishment, this return is certainly favorable, for such a resolve to chose the good things brings its own reward.
