Leaves on a stream
You picture thoughts as leaves floating past — practising watching thoughts instead of living inside them.
Leaves on a stream is an image in which you sit beside a stream and place each thought that appears on a leaf that floats away. You do not try to push it off and you do not hold it back; you simply watch it pass. Almost everyone finds that the stream disappears and they end up inside a thought — at which point you put the stream back without reproach. That happens ten times in eight minutes, and it is the point of the exercise. If water does not suit you, use clouds, a conveyor belt or railway carriages; the image does not matter, the passing does.
When to use it
With rumination and with thoughts that keep repeating. The exercise comes from acceptance and commitment therapy.
How it goes
- Close your eyes and picture a slow stream carrying leaves.
- Place each thought that comes on one leaf and let it float away.
- Don’t try to speed the stream up, and don’t push the leaves along.
- When you notice you are in a thought again rather than beside the stream, simply return to the bank.
Why it works
It doesn’t remove thoughts. It practises the difference between having a thought and being the thought — which, with rumination, is the crucial difference.
