When worries start piling up, it can feel as though the mind is running on a loop. A difficult conversation, a looming deadline, or concerns about the future can keep returning long after the moment has passed.
One mindfulness practice that aims to help people step back from these thoughts is called Leaves on a Stream meditation. The exercise is widely used in Acceptance and Commitment Therapy (ACT), a psychological approach developed by psychologist Steven C. Hayes.
Rather than encouraging people to push away unwanted thoughts, the exercise teaches them to observe those thoughts without getting caught up in them.

What is leaves on a stream meditation?
The practice uses a simple mental image.
Imagine yourself sitting beside a gently flowing stream. Every time a thought enters your mind, place it on a leaf floating on the water. Then watch the leaf drift away.
The thought could be about work, family, finances, relationships, or something that happened earlier in the day. Whatever appears, the idea is to acknowledge it and place it on a leaf without judging it.
Soon, another thought may arrive. That thought goes on a new leaf and continues downstream. The goal is not to stop thinking. Instead, it is about learning to notice thoughts without becoming overwhelmed by them.
How is the exercise connected to acceptance and commitment therapy?
Leaves on a Stream meditation is often used to teach a concept known as “cognitive defusion.”
According to Hayes and other ACT practitioners, people often become fused with their thoughts, meaning they treat every thought as a fact or something that demands an immediate reaction.
The exercise encourages the opposite approach.
By imagining thoughts floating away on leaves, people practice creating some distance between themselves and what they are thinking. This can help them recognise that thoughts are temporary experiences rather than permanent truths.
Why do mindfulness practitioners recommend it?
Many people begin meditation expecting a completely quiet mind. However, mindfulness teachers often point out that thoughts naturally come and go.
The purpose of Leaves on a Stream meditation is not to eliminate thoughts but to change the relationship a person has with them.
Some practitioners find that the exercise helps them become more aware of recurring worries and mental habits. Others use it as a way to pause before reacting to stressful situations.
Because the practice focuses on observation rather than control, it can be accessible even for people who are new to meditation.
How can beginners try it?
The exercise requires no special equipment.
Find a quiet place to sit comfortably and take a few slow breaths. Picture a stream flowing at a natural pace. As thoughts arise, place each one on a leaf and watch it move along the water.
If a thought returns, place it on another leaf.
There is no need to force thoughts away or try to clear the mind. The practice is simply about noticing what appears and allowing it to pass.
