Nine in the second place means:
This refers to the involuntary influence of a man's inner being upon persons of kindred spirit. The crane need not show itself on a high hill. It may be quite hidden when it sounds its call; yet its young will hear its not, will recognize it and give answer. Where there is a joyous mood, there a comrade will appear to share a glass of wine.
This is the echo awakened in men through spiritual attraction. Whenever a feeling is voiced with truth and frankness, whenever a deed is the clear expression of sentiment, a mysterious and far-reaching influence is exerted. At first it acts on those who are inwardly receptive. But the circle grows larger and larger. The root of all influence lies in one's own inner being: given true and vigorous expression in word and deed, its effect is great. The effect is but the reflection of something that emanates from one's own heart. Any deliberate intention of an effect would only destroy the possibility of producing it.
Confucius says about this line:
The superior man abides in his room. If his words are well spoken, he meets with assent at a distance of more than a thousand miles. How much more then from near by! If the superior man abides in his room and his words are not well spoken, he meets with contradiction at a distance of more than a thousand miles. How much more then from near by! Words go forth from one's own person and exert their influence on men. Deeds are born close at hand and become visible far away. Words and deeds are the hinge and bowspring of the superior man. As hinge and bowspring move, they bring honor or disgrace. Through words and deeds the superior man moves heaven and earth . Must one not, then, be cautious?
