Hexagram 42: Increase (益)

Hexagram 42, Yi (益), places Wind above Thunder — two active forces reinforcing each other, each amplifying the other's momentum. In the I Ching, this image describes a period of genuine increase: effort produces more than usual return, conditions are favorable, and the capacity to grow and to help others grow simultaneously is present. The classical Judgment reads: "growth is favorable when it benefits more than the self."

The hexagram is paired with Hexagram 41 (Decrease) and understood as its complement. Where decrease asks for voluntary simplification, increase asks for generous expansion. The King Wen sequence treats the two as a continuous cycle: the sincerity developed through decrease creates the quality of character that makes increase genuinely beneficial rather than merely accumulative.

The image says: "Wind and thunder increase; move toward useful action." The I Ching commentary on this hexagram describes the wise person as someone who, upon seeing good in others, moves toward it and emulates it; upon seeing their own faults, corrects them. The practical lesson is that a period of increase is best used not just for accumulation but for genuine development — of capability, of character, and of the relationships that make growth sustainable.

The hexagram also supports crossing great rivers — taking on significant challenges during a period of favorable conditions. The wind and thunder together create more than either alone; the moment of increase is the moment to attempt what would be too difficult under ordinary conditions.

In career contexts, Hexagram 42 often appears during a period of genuine momentum — a successful project, a favorable market, or a relationship with a mentor or sponsor that is producing real opportunity. The hexagram supports moving forward actively and asks for the generosity to share the growth: investing in others, building durable structures, and using the favorable period to create something that will outlast the conditions that produced it.

In decision contexts, it describes a moment when the risk-reward ratio is genuinely favorable — when attempting something significant is more likely to succeed than usual. The classical support for crossing great rivers applies: this is the time to take on the challenge you have been preparing for.

Hexagram 42 is not a guarantee that all growth will continue indefinitely or that favorable conditions are permanent. The cycle of increase and decrease is continuous — the I Ching places Hexagram 43 (Breakthrough) after Increase, suggesting that the energy of growth eventually reaches a point where it must be expressed or released decisively. Using a period of increase to build something durable is wiser than assuming the conditions will last.

It is also not saying that all increase is beneficial. Growth that benefits only the self at the expense of others is not what this hexagram describes — the classical emphasis on outward benefit is not decorative. Increase that flows outward creates the conditions for continued growth; increase that is hoarded tends to produce the conditions for its own reversal.
