Trigram breakdown
Upper · Mountain · 艮
Yang resting on two yins. The line that says no further. Containment as discipline.
Lower · Lake · 兌
Yang doubled below, yielding above. Joyfulness that overflows its banks.
Judgment
'Decrease' describes the moment when something must be given up to allow something of greater value to consolidate and grow. The Mountain sits above the Lake, pressing down, drawing moisture upward into itself - the lower gives to the upper, the outer yields to the inner. This is not loss for its own sake but purposeful reduction: trimming away what is excessive so that what is essential can strengthen. What looks like sacrifice from the outside is, in the right context, an act of genuine increase.
Image
When a mountain sits above a lake, it draws the lake's water upward through evaporation, reducing the visible surface while feeding hidden springs and deepening the mountain's interior. The lake gives, the mountain receives, and neither is diminished in any lasting way. This teaches that voluntary reduction - offered willingly and at the right moment - circulates energy rather than losing it.
Essence
Character
This person trims by instinct. A crowded calendar, a pile of promises, a habit that stopped paying its way: they cut it back without much fuss. Because of this, they often see clearly what matters. Others read the ease as wisdom, and often it is. The weak spot is that giving can turn into a way of proving they are sincere. They offer too much too early and ask for little. Their own needs go first on the list to be cut. Then they run thin and say nothing. They do best when they ask what the cutting is for, and keep what answers that question.
With other people
In a group, this person becomes the one who lightens the load. They drop a bad plan, take on the dull task, and shrink their own claim so the work can move. The catch is that others come to expect it and stop noticing the cost. Played well, they give with a clear reason, say what they need, and let the group carry some of the weight too.
Mountain over Lake
Lake within wants to give, to pour out warmth and goodwill, while Mountain without holds a firm line and keeps what matters still.
The six lines
Hexagram 41 Line 1 (41.1)
A yang line at the base - solid strength at the foundation - can afford to give without being depleted. Helping others now does not weaken your position; it is the right moment to share resources or effort, as long as you assess honestly how much can actually be given.
Hexagram 41 Line 2 (41.2)
The second yang line holds real capability but must not give itself away completely in the name of generosity. True decrease here means maintaining your own integrity while contributing to the situation above - an empty vessel cannot pour.
Hexagram 41 Line 3 (41.3)
Three yin lines occupy the Human positions, and this third line sits at the lower threshold of that zone. When three people travel together, one naturally departs; when two travel, a companion is gained. This line signals that the group dynamic is in flux, and honest reduction of competing voices clarifies the path forward.
Hexagram 41 Line 4 (41.4)
The fourth yin line, in the upper Human position, reflects a person who has been carrying a burden of flaw or difficulty. Decreasing that weakness - through honest effort rather than pretense - attracts those who can genuinely help, turning a private struggle into a basis for connection.
Hexagram 41 Line 5 (41.5)
The ruler's line is yin here, suggesting receptive rather than commanding leadership. What comes to this position does not need to be sought or forced - it arrives as a natural consequence of the decrease below. Accept what is offered without grasping and it will genuinely increase your situation.
Hexagram 41 Line 6 (41.6)
The top yang line is the culmination of the entire decrease process, and here the dynamic inverts: to increase without taking from others. This is the point where personal decrease has fully served its purpose and what was given away returns transformed. The self-imposed restriction is over and expansion is now legitimate.

Gate 41 in Human Design
In Human Design, Hexagram 41, Decrease, is Gate 41, with the same six lines. It sits in the Root Center, and its one channel connects it to Gate 30 in the Solar Plexus Center. How to read your gates in the I Ching
The reading goes further down
What you have read here is the shape of Hexagram 41, 'Decrease'.
Underneath it sit four more: the mechanic that drives it, the shadows it casts, the way through them, and the tension between Mountain and Lake that never quite settles.
And if this hexagram appeared in your Birth Hexagram Triad, one of its six lines is changing. That line is your growth edge, named out loud.
