Observing thoughts as arising and passing events
Treat each thought as weather — it arrived, it will leave — rather than as a statement about reality.
Why it works
Thoughts feel permanent and substantial because they arrive with the implicit claim of truth. Observing that each thought arises from conditions (a memory, a sense impression, a mood state) and passes when those conditions shift reveals the thought as an event rather than a fact. This is the basis of cognitive defusion in ACT and of insight into anatta: the thought is not "me thinking" but "thinking arising."
How to do it
- In meditation, when a thought appears, note: "thinking… arising… there it is…"
- Observe the thought as an object — where is it? Does it have a shape, a texture, a weight?
- Watch it change or dissolve — without engaging its content.
- If it pulls you in, return to the breath and note "thinking" again, without self-judgment.
Evidence
Cognitive defusion — treating thoughts as events rather than facts — is a central ACT skill with growing evidence for reducing the distress impact of intrusive thoughts. A controlled component study found that a brief defusion technique applied to self-relevant negative thoughts reduced their believability and discomfort more than distraction or thought-control, isolating the defusion move itself as the active ingredient. (clinical)
Levin et al. study ACT components; the Buddhist anicca framing is traditional but shares the defusion mechanism.

Common mistake
Noting "thinking" as a judgment ("I should not be thinking") — the note is neutral observation, not a command to stop.

More practices for Anicca: Working Practically with Impermanence
- Sensation-level impermanence noting
In meditation, track how quickly every physical sensation arises and passes away.
- Riding the emotion wave with anicca awareness
When a strong emotion hits, track it through its full arc — notice it peak and fall without fleeing or amplifying.
- The impermanence gratitude turn
Use the awareness that pleasant things are temporary to intensify genuine appreciation for them while they are here.
- Integrating loss through the lens of anicca
When grieving a loss, ground the experience in the insight that what ended was always impermanent — and that grief itself is impermanent.
- Applying anicca to the self-concept
Notice that the "self" you identify with right now is a temporary configuration — different from who you were five years ago and who you will be.
