The earth above the lake:
The image of Approach.
Thus the superior man is inexhaustible
In his will to teach,
And without limits
In his tolerance and protection of the people.

The earth borders upon the lake from above. This symbolizes the approach and condescension of the man of higher position to those beneath him. The two parts of the image indicate what his attitude toward these people will be. Just as the lake is inexhaustible in depth, so the sage is inexhaustible in his readiness to teach mankind, and just as the earth is boundlessly wide, sustaining and caring for all creatures on it, so the sage sustains and cares for all people and excludes no part of humanity.
