The Book of Successful Contemplation (Ying-kuan-ching) says: "The sun sinks in the great water and magic pictures of trees in rows arise". The setting of the sun means that in chaos (in the world before phenomena, that is before the intelligible world) the foundation is laid: that is the non-polarized condition [ultimateless]. Highest good is like water, pure and spotless. It is the ruler of the great polarity, the god who appears in the trigram of shock, Chen. Chen is also symbolized by wood, and soothe image of trees in rows appears. A sevenfold row of trees means the light of the seven body-openings (or heart-openings). The northwest is the direction of the Creative. When it moves on one place further, the Abysmal is there. The sun which sinks on one place further, the Abysmal is there. The sun which sinks into the great water is the image for the Creative and the Abysmal. The Abysmal is the direction of midnight (mouse, tzu, north). At the winter solstice, thunder (Chen) is in the middle of the earth quite hidden and covered up. Only when the trigram Chen is reached does the light-pole appear over the earth again. That is the image represented by the rows of trees. The rest can be correspondingly inferred.
