Hexagram 42, Yi (Increase)

Hexagram 42, Yi, arrives as one of the I Ching”s most directly favorable signs: a genuine period of increase, abundance, and expanding opportunity. When Yi appears in a reading, the oracle confirms that the conditions are genuinely generous and that the time is right to act on important undertakings, to cross great rivers, and to extend generosity outward from whatever abundance is available. The hexagram honors not just the fact of increase but the quality of how it is used.

The character yi means to increase, benefit, or add to, and carries the sense of genuine augmentation rather than mere redistribution. What increases in Yi does so from actual growth rather than from taking from another; the image is of the ruler who draws from the treasury of Heaven itself to benefit the people, a generosity that diminishes no one.

History and origins

The classical commentary on Yi makes explicit the ethical dimension of increase: decrease that comes from above and benefits those below is the source of the people”s joy, and a properly functioning ruler or leader practices this kind of downward generosity as the appropriate use of their position. This framing connects Yi directly to the Confucian ideal of benevolent governance: those who have received abundance are morally called to share it in ways that benefit the broader community.

The commentary also notes that the wise person, upon seeing goodness, moves toward it and imitates it; upon seeing faults, corrects them. Increase in Yi is not passive; it calls for active movement toward what is good and active correction of what is not. The favorable conditions require the questioner”s engaged participation in order to be fully realized.

Yi and Sun form one of the I Ching”s most important paired relationships, modeling the natural cycle of generosity and cultivation. Sun described what is willingly given away; Yi describes what genuinely grows. Together they suggest that generosity and increase are not opposites but parts of a single organic process.

In practice

When Yi appears in a reading, the questioner is in a genuine period of abundance or expanding opportunity, and the hexagram”s counsel is to act. The I Ching is quite clear: this is not a time for excessive caution, for hoarding, or for waiting. The conditions favor forward movement, and the hexagram specifically endorses crossing great rivers, taking on significant undertakings.

The ethical dimension of Yi”s counsel is equally clear: use the abundance well. Share it appropriately with those who would benefit. Do not contract around the increase out of fear of losing it; the generosity of Yi is self-renewing when genuinely practiced.

The hexagram also asks the questioner to notice and imitate genuine goodness encountered during this period. A time of increase is also a time of heightened sensitivity to models of excellence; those who are genuinely admirable during Yi”s period become teachers for the questioner”s own development.

A method you can use

When Yi appears, engage with its energy through a practice of generous action.

Begin by honestly acknowledging what has genuinely increased in your life, circumstances, or capacity. Do not minimize this out of modesty or superstition about acknowledging good fortune; Yi asks for honest recognition of real abundance.

Identify one specific way you can use what has increased to benefit someone or something beyond yourself. This might be a practical contribution, a sharing of knowledge or resources, an introduction or recommendation, or simply genuine attention and care given to someone who needs it.

Take that action without delay. Yi”s abundance is connected to its generosity; hoarding or contracting around good fortune runs counter to the hexagram”s essential principle.

Then take the forward step you have been considering. Yi specifically endorses the crossing of great rivers: significant, meaningful undertakings that the questioner has been preparing for. Now is the time.

Trigram structure and symbolism

Wind (Xun) above Thunder (Zhen) creates a notably dynamic combination. Thunder below initiates from the ground upward with awakening force; Wind above descends and penetrates from above. The two forces move toward each other and reinforce each other”s movement, creating a circulation of energy in both directions simultaneously. This mutual reinforcement is the structural image of genuine increase: not extraction from one direction but augmentation from both.

The combination of Wind”s penetrating persistence and Thunder”s initiating force creates the conditions for growth that reaches everywhere. Wind disperses seeds; Thunder wakes what is dormant. Together they describe the ideal conditions for all forms of increase.

Changing lines

The changing lines of Yi address different positions within the period of increase. The first line describes someone who should not do great things alone, but who in a great work brings good fortune and no blame; increase from below is appropriate when the timing is right. The third line shows increase in difficult circumstances, but sincerity and walking in the middle road brings good fortune even here. The fourth line describes walking in the middle ground: informing the ruler about the situation and acting as a faithful representative brings trust and enables forward movement. The fifth line shows the increase of genuine good-heartedness: the great person”s virtue is so evident that no questioning is needed. The sixth line warns against increase that does not distribute to others: someone who only draws toward themselves without sharing will eventually attract what they do not want.

In divination

Yi appears in readings about periods of genuine abundance and opportunity, about the right time to take significant action, about the use of resources and good fortune, and about the ethical dimensions of having more than one needs. It affirms that the conditions genuinely favor forward movement and confirms that generous, well-directed action during this period will produce lasting results. It is one of the I Ching”s most unambiguously favorable hexagrams when the questioner is asking whether to move forward.

Yi”s deepest teaching is that genuine increase, like the spring rains that benefit every living thing rather than only a chosen few, is most fully itself when it is shared.

In myth and popular culture

Abundance and the ethics of what is done with genuine good fortune are among the most examined themes in world religious and philosophical literature. The parable of the talents in the Christian Gospels, in which servants are given different amounts of money by their master and are judged on what they do with it, engages Yi’s territory directly: genuine increase is understood as an opportunity and a responsibility, not merely a windfall to be enjoyed passively.

In Confucian political philosophy, the ruler who shares their abundance downward to benefit the people is the central model of legitimate governance. The concept of the benevolent ruler, the wang, whose virtue flows outward to benefit all under Heaven, is the political expression of Yi’s teaching that increase is most genuinely itself when it is generously shared. The classical commentary’s account of the ruler drawing from Heaven’s surplus to benefit the people articulates exactly this principle.

In Hindu tradition, the concept of dana, charitable giving, is understood as one of the three primary virtues alongside tapa (ascetic practice) and yajna (ritual offering). Dana during periods of abundance is treated not as optional generosity but as a fundamental obligation that maintains the circulation of benefit through the cosmos. This cosmological understanding of generosity as sustaining the system that produces abundance, rather than merely depleting a private store, is structurally identical to Yi’s teaching.

In twentieth-century economic thought, the concept of the multiplier effect, where money spent circulates through an economy and produces more total economic activity than the original expenditure, is a secular version of Yi’s understanding that genuine, well-directed increase circulates and grows rather than concentrating. The Depression-era economic programs of the New Deal were partly built on this understanding: that public investment during a period of shortage could initiate a cycle of increasing activity.

Myths and facts

Several beliefs about increase, abundance, and this hexagram deserve examination.

• A common assumption holds that Yi is a simple “good luck” hexagram that requires nothing from the questioner. The hexagram consistently connects favorable conditions with the questioner’s active participation; the crossing of great rivers endorsed in the Judgment requires the questioner’s decision and effort.
• Many readers assume that Yi confirms whatever the questioner was already planning to do. The hexagram endorses genuinely forward-looking action and the sharing of increase; it is not a blank endorsement of any current plan regardless of its actual merit.
• It is sometimes assumed that the ethical dimension of Yi’s counsel, sharing abundance appropriately, is optional or secondary to its affirmation of favorable conditions. The classical commentary treats the generosity aspect as structurally central to what makes the period’s increase genuine and self-sustaining.
• Some practitioners interpret Yi as promising that the current period of increase will continue indefinitely. The I Ching’s cyclical understanding makes clear that increase has its season, as does decrease; Yi’s counsel to act while conditions are favorable implies that they will not always be so.
• A widespread belief holds that acknowledging good fortune openly will somehow diminish or reverse it. Yi specifically asks for honest recognition of what has genuinely increased; the hexagram does not endorse false modesty or superstitious avoidance of acknowledging abundance.
