Introduction

The strong trigram Chên is above, the weak trigram Sun below. This hexagram is the inverse of the preceding one. In the latter we have influence, here we have union as an enduring condition. The two images are thunder and wind, which are likewise constantly paired phenomena. The lower trigram indicates gentleness within; the upper, movement without.

In the sphere of social relationships, the hexagram represents the institution of marriage as the enduring union of the sexes. During courtship the young man subordinates himself to the girl, but in marriage, which is represented by the coming together of the eldest son and the eldest daughter, the husband is the directing and moving force outside, while the wife, inside, is gentle and submissive.
