Balancing Weak and Strong Points - Let Your Thoughts Flow Like Water (Chapter 6)
Your neighbor starts mowing the lawn right as you sit down for a quiet Sunday meal.
Frustration hits. Then annoyance. Then a whole story about how the world is against you. Before you know it, your peaceful afternoon is gone, and all that changed was some noise outside.
Sun Tzu’s Chapter 6, “Balancing Weak and Strong Points,” is about exactly this. How one small thought grabs hold, multiplies, and takes your whole mind hostage. And what you can actually do about it.
Show Up Ready
Sun Tzu opens with a battle principle that works perfectly for the mind: the student who is waiting and ready when trouble arrives will have energy to handle it. The one who shows up late to the fight will already be exhausted.
Applied to thinking, this means: if you know certain situations are going to trigger you, prepare for them. You already know which coworker gets under your skin. You know which family member’s comments will sting. You know the traffic route that makes you rage.
So instead of walking into those moments on autopilot, walk in aware. Ready. With your concentration already rooted.
Because here’s what Sun Tzu says: “The student who controls the flow of mental thoughts will make it impossible to be controlled by them.”
That’s the whole chapter in one line.
Weak Thoughts vs. Strong Thoughts
Not all thoughts are equal. Some pass through your mind like clouds, barely leaving a mark. Those are weak thoughts. You can let them go without effort.
Then there are strong thoughts. The ones attached to deep emotions. Old wounds. Long-standing patterns. These are the thoughts that grab you by the collar and drag you down a rabbit hole of more thoughts, more emotions, more suffering.
Sun Tzu wants you to learn the difference. Recognizing which thoughts are weak (and can be released easily) versus which are strong (and need careful attention) is a core skill on this path.
The goal is always the same: keep balance. Don’t let a weak thought build into a strong one. And when a strong thought shows up, don’t panic. You can still work with it.
The Fluid Mind
This is the big idea of the chapter. Sun Tzu says the mind works best when it’s fluid. Flexible. Moving. Like water.
When you grab onto a thought and hold it still, you give it power. It takes root. It multiplies. It calls in reinforcements, more emotions, more memories, more stories. Suddenly one thought has become an army invading your peace.
But if you let thoughts flow through without grabbing them? They pass. Like water over rocks. They don’t stick. They don’t multiply. Your mind stays calm.
The metaphor Sun Tzu uses: “Mental battles are like water that runs its course naturally from high to low places, unrestricted.”
Let the water flow. Don’t build dams.
The Blue Cows Technique
And here’s where it gets fun. Sun Tzu says that sometimes, a thought has gotten so deep, so rooted, that you can’t just “let it go.” It’s too strong. Your concentration is shattered.
His advice? Throw something weird at your mind.
The book gives a hilarious example. Say your neighbor is mowing and you can’t break the thought-thread of frustration. So imagine there are cows outside making the noise instead. Blue cows. Climbing on the roof. Jumping over the moon. Bells clanging.
Sounds ridiculous, right? But that’s the point. The absurdity interrupts the pattern. Your brain literally can’t stay on the frustration train while also picturing blue cows on a roof. The thought-chain breaks. You get a moment of mental space. And in that space, you can re-center.
This is basically what Sun Tzu meant by: if you’re too weary to regain concentration, “throw something odd and puzzling at the mind to slow it down.”
It works. Try it.
Break the Chain, Don’t Fight It
One of the most practical ideas in this chapter is the concept of dividing thought-chains. Instead of trying to stop a powerful thought head-on (which usually makes it stronger), you break it into smaller pieces.
Think about it like this. Someone interrupts you mid-sentence and you lose your train of thought completely. We’ve all experienced that. Sun Tzu says you can do that to yourself on purpose.
When a thought-chain is running wild, interrupt it. Shift your focus to something else. Focus on your breath. Look at something specific in your environment. Count backwards. Anything that breaks the thread.
Once the chain is broken into pieces, those pieces are weak. They can’t overwhelm you the way the whole chain could. You’ve divided the army, and now you can handle each small group one at a time.
Your Mind Creates the Noisy Neighbor
Here’s where the chapter gets deeper. The neighbor mowing the lawn is just a person mowing their lawn. That’s it. Only your mind decided it was a problem.
Sun Tzu pushes this further: if your mind stopped making judgments entirely, what would the world look like? Not disruptive. Just still. At peace.
And here’s the real kicker. When you free yourself from the thought that your neighbor is a nuisance, you also free them. They stop being “the annoying neighbor” in your reality. They just become a person doing yard work. Your changed perception changes everything.
The book says our emotions about situations, especially the strong ones, are often rooted in the past. Maybe you were a quiet kid who hated loud noises. That old pattern is still running the show decades later. The neighbor isn’t really the problem. The unexamined thought pattern is.
Cycles of Growth
Sun Tzu says mental growth happens in seasons. Sometimes you’ll feel like you’re making real progress, shifting perceptions, overcoming old patterns. Other times you’ll feel stuck. Transitioning. Like winter.
Both are normal. Both are part of the cycle.
The wise student, Sun Tzu says, stays “bending and flexible no matter the season.” Just because you feel stuck doesn’t mean you’ve failed. Just because you feel great doesn’t mean you’re done.
Stay flexible. Stay aware. The seasons keep turning.
Inner Creates Outer
There’s a beautiful idea tucked into this chapter. As your thoughts change, your perception of the world changes too. You start seeing less separation and more connection. Less conflict and more harmony.
Eventually, Liguore writes, you may recognize that you’re actively shaping the world around you with your thoughts. When you slip up and become mentally disordered, your outer world takes on that same confused quality. When you restore your inner calm, the world around you also feels more harmonious.
It’s not magic. It’s perception. And perception is everything.
What You Can Do Today
Take inventory. Right now, what thoughts are sitting in your mind? Which ones are weak, just passing through? Which ones are strong, hooked into deep emotions?
For the weak ones: let them go. Don’t even engage.
For the strong ones: don’t fight them head-on. Break the chain. Interrupt the pattern. Throw some blue cows at it if you need to.
And if a thought keeps coming back, in cycles, repeating the same pattern over and over? That’s not a bug. That’s the curriculum. That’s your mind showing you exactly what you need to work on next.
Our habituated thought-threads are not concrete, though it can seem like it. With time, the more we unseat these enemies-of-thought, the more likely we will discover freedom and a new way of life will open up for us.
