Decrease. The Sequence of the Hexagrams states: 'Deliverance means relaxation. Relaxation inevitably brings loss; hence it is received with Decrease.' Indulging in relaxation inevitably causes loss, and loss is decrease; thus Decrease succeeds Deliverance.
As a hexagram, Gen is above and Dui is below: the Mountain's body is tall, and the Lake's body is deep. When the lower is deep, the upper becomes even higher, bearing the meaning of decreasing what is below to increase what is above.
Moreover, the Lake lies beneath the Mountain; its vapor ascends to nourish grass, trees, and all creatures, which is also decreasing what is below to increase what is above.
Furthermore, below is Dui (Joyous), whose three lines all correspond above, pleasing in order to serve the superior—another meaning of decreasing the lower to increase the upper.
Also, the lower Dui became Dui through the change of Six in the Third Place, and the upper Gen became Gen through the change of Top Nine: the third was originally firm but became yielding, while the top was originally yielding but became firm, which is likewise decreasing the lower to increase the upper.
Decreasing the upper to increase the lower is Increase; taking from the lower to increase the upper is Decrease. When those who stand above others extend their bounty down to the lower, that is increase; when they take from the lower to enrich themselves, that is decrease.
For example, in piling earth, if one decreases from the top to thicken the foundation, both top and bottom remain secure and solid—how could that not be an increase?
But if one takes from the foundation to augment the height above, peril and collapse will arrive—how could that not be a decrease? Therefore Decrease has the meaning of decreasing the lower to increase the upper, while Increase is the opposite.
Decrease means diminishing and cutting down. In all things, restraining excess to approach justice and principle is the way of decrease. The way of decrease must possess confidence and sincerity, meaning ultimate sincerity that accords with principle.
When decreasing accords with principle, it is supremely good and auspicious; what is decreased has no error, can be perseveringly maintained as a constant practice, and it is advantageous to have somewhere to go.
When what people decrease is either excessive, deficient, or inconstant, none of it conforms to correct principle, nor does it possess confidence.
Without confidence, there is no auspiciousness but rather blame; it is not a way that can be maintained with constancy, nor can it be practiced. Decrease means diminishing excess to reach the mean, trimming trivial superficialities to return to the fundamental reality.
The Sage regarded frugality as the root of propriety. Therefore, to illuminate the meaning of Decrease, he spoke in terms of sacrifices: the rites of sacrifice are of the most elaborate elegance, yet sincerity and reverence are their foundation.
An abundance of ceremonies and full provision of offerings are meant to convey that sincere and reverent heart. When adornment exceeds sincerity, it turns into hypocrisy; decreasing adornment preserves sincerity. Hence it says, 'What should be used?
Two simple baskets may be used for the offering.' The austerity of two baskets suffices for sacrificial offerings, meaning that everything lies in sincerity alone; sincerity is the root.
None of the world's harms fail to arise from the superficial overcoming the fundamental: lofty towers and carved walls originate in dwellings; ponds of wine and forests of meat originate in food and drink; cruel severity and brutality originate in punishments; exhaustion of the military and reckless warfare originate in punitive expeditions.
All excesses of human desire originate in sustenance and maintenance; when their divergence spreads far, they become ruinous. The early kings regulated the fundamentals according to heavenly principle; later generations drifted into superficialities through human desire.
The meaning of Decrease is simply to decrease human desires in order to restore heavenly principle.
