Permanent change : is close to Anicca, not close to Anatta. Anatta is the opposite to "Atta". Atta is the feeling that, There is someone living inside and that feeling create "I". Atta like paper mache, Nothing inside but we create paper mache. Anatta is "No I". If we merge "Atta" with "Opinion". Then "I'm right" will be arised. If we don't merge, it is just an opinion. Right or Wrong ... does not matter.
