Have you ever had a thought that just wouldn’t leave you alone? A worry, a self-criticism, or a painful memory that plays on a loop, no matter how hard you try to push it away. It’s like a song stuck in your head, but instead of a catchy tune, it’s a distressing feeling.
Our natural instinct is to fight these thoughts. We argue with them, we try to suppress them, we distract ourselves. But often, this struggle just makes the thought stickier. It’s like trying to hold a beach ball underwater—the harder you push it down, the more forcefully it pops back up.
But what if the goal wasn’t to fight the thoughts, but to change your relationship with them entirely? What if you could learn to just let them float by? This is the essence of the Thought River, a gentle yet profound mindfulness exercise. As the mindfulness pioneer Jon Kabat-Zinn says:
“You can’t stop the waves, but you can learn to surf.”
The Thought River teaches you how to surf the waves of your own mind.
The Trap of ‘Thought Fusion’
In modern psychology, particularly in Acceptance and Commitment Therapy (ACT), the state of being tangled up in our thoughts is called Cognitive Fusion. It’s when we are so “fused” with our thoughts that we treat them as literal truths or direct commands. The thought “I am a failure” is experienced not as a string of words, but as an absolute reality.
The antidote to this is Cognitive Defusion. This is the skill of learning to step back and see our thoughts for what they truly are: just internal events. They are simply words, images, and sensations passing through our awareness. They are not facts, and they are not in charge of us. The Thought River is a beautiful way to practice this skill.
How to Practice the Thought River Exercise: A Step-by-Step Guide
Find a comfortable place to sit where you won’t be disturbed for 5-10 minutes. Allow your eyes to gently close.
Step 1: Picture the Scene
Imagine yourself sitting on the grassy bank of a beautiful, gently flowing river. See the water moving, the sunlight dappling on its surface. Hear the soft, bubbling sounds. Feel the warmth of the sun or the cool breeze on your skin.
Step 2: Notice Your Thoughts
Now, turn your attention inward. Your mind will naturally produce thoughts. Your task is not to change or stop them, but to simply notice them as they arise, like a curious and gentle observer.
Step 3: Place Each Thought on a Leaf
As a thought comes into your awareness—whether it’s a single word, a sentence, a worry, or an image—imagine placing it onto a leaf that is floating on the river.
Step 4: Watch It Float By
Without pushing or hurrying it, simply watch the leaf as it is carried by the current. Watch it float into your field of vision, and then watch it drift away downstream, eventually disappearing from sight.
Step 5: Repeat, Gently
Another thought will come. Do the same. Place it on a new leaf and watch it float by. Some thoughts might be big, some small. Some might be “sticky” and float by several times. That’s okay. Your only job is to remain on the riverbank, placing each thought on a leaf and letting the river do the rest. If you find you’ve gotten “in” the river and have been carried away by a thought, simply and kindly guide yourself back to your seat on the riverbank and start again.

You Are the Riverbank, Not the River
This exercise teaches you a profound truth: you are not your thoughts. You are the space in which the thoughts occur. The river of your mind will always be flowing—sometimes fast, sometimes slow, sometimes clear, sometimes muddy. Your peace doesn’t come from trying to control the river. It comes from learning to rest on the bank, stable and present, allowing the current to flow by without being swept away by it.
