What this hexagram is about
I Ching hexagram 42, Gaining, is about growth that comes when you move toward what is good and correct what is wrong. The name in Chinese is 益, which means gain or increase, and the picture is of wind and thunder working together.
The upper trigram is Wind, 巽, which moves gently and spreads everywhere. The lower trigram is Thunder, 震, which rises with a sudden burst of energy. Together they suggest a moment when something pushes you forward from below while something else carries that push outward, like a storm that clears the air and feeds the ground.
This is not gain that falls into your lap. It is gain you take part in, by seeing what is better and going toward it, and by noticing your own faults and fixing them. The hexagram asks you to be active, not passive, and to use the increase you receive for work that matters.
The Judgment in plain words
The Judgment says: "It is favourable to have somewhere to go. It is favourable to cross the great river." This means the moment favors action, and not just small action. Having somewhere to go means you have a direction, a purpose that pulls you forward. Crossing the great river means taking on something risky and demanding, something that requires real effort.
The two phrases work together. You are not asked to wander or to gamble. You are asked to set a course and then commit to it, even if the crossing looks dangerous. The gain here comes through movement, not through waiting.
What this asks of you is simple to say and hard to do: choose where you are going, and then go. If you hesitate, the increase stalls. If you move with sincerity and a clear aim, the water parts, or you find the boat. The favorable reading is not a promise, it is an invitation to act.
The Image
Wind and thunder together make the scene of this hexagram. Thunder rises from the earth with force, and wind follows, carrying that force across the landscape. You can picture a storm building, the air changing, and then the rain reaching places that were dry.
The noble person sees this and acts in two ways. Seeing good, they move toward it, like turning your face to the wind. Having faults, they correct them, like clearing the ground after the storm. The image is not about watching the weather, it is about using the energy it brings.
For you today, this might mean noticing a good example and following it, or admitting a mistake and changing course. The gain comes from the movement itself, from the willingness to shift. What you add to yourself, you add by what you do, not by what you merely admire.
The six lines
Line 1, 初九, says it is favorable to use this for great work, with great good fortune and no blame. This is the bottom line, the start of the movement. At the beginning, you have the energy to build something large, and the moment supports it. Do not think small here. The work you start now can carry real weight.
Line 2, 六二, says perhaps someone gives to you, and a tortoise worth ten strings of cowries cannot be refused. Holding steady brings good fortune, and the king uses this to make offerings. This line speaks of a gift from outside, something so valuable you cannot turn it down. Your part is to receive it with steadiness, not to chase it or doubt it.
Line 3, 六三, says use this gain in times of misfortune, with no blame. With sincerity, walk the middle path, and when you report to the lord, carry a jade tablet. This line points to trouble, but the gain is meant for exactly that moment. You use what you have to meet the difficulty, and you report honestly, with proper form.
Line 4, 六四, says walking the middle path, you report to the lord and he follows. It is favorable to use this to move the state's capital. This line is about influence and change on a larger scale. You speak clearly and act with balance, and those in authority listen. The gain becomes big enough to shift foundations.
Line 5, 九五, says holding sincerity, you show kindness to the people. Do not ask. Great good fortune. Holding sincerity, your kindness reaches my virtue. This is the central line, the heart of the hexagram. You give without calculating, and the good returns by reaching others. The kindness you offer becomes part of who you are.
Line 6, 上九, says no one adds to him, and some even strike him. He sets his heart without constancy. Misfortune. This is the top line, where gain has turned to excess. You have taken too much or held on too long, and the increase stops. The warning is against an unsteady heart, one that cannot stay true to its course.
When it comes up in your cast
When this hexagram comes up in your cast, it suggests that your question is about a moment of possible increase. Whether you asked about love, work, or a decision, the answer points the same way: move toward what is good, and correct what is wrong. This is a time for action, not for standing still.
If you have moving lines, read their texts closely, because they mark the places where the situation is shifting. Those lines also turn this hexagram into a second one, which shows where the movement leads. The inner hexagram here is Stripping Away, 剝, which reminds you that gain can also peel back what is false, so what remains is only what is real.
Remember that the I Ching is for reflection and entertainment. It helps you look at your question from a new angle, but it does not decide for you. Let this hexagram open your eyes to the good you can move toward and the faults you can correct, then make your own choice with a steady heart.
