Having attempted to understand the actualization of `Anatta`, i am at a complete loss. The more i endeavor to understand the meaning, the more confusing it seems. 

I have read;

1. [What is the best translation of Anatta into English?](https://buddhism.stackexchange.com/questions/2500/what-is-the-best-translation-of-anatta-into-english)
2. [What is the precise meaning of anatta?](https://buddhism.stackexchange.com/questions/1891/what-is-the-precise-meaning-of-anatta)
3. [No-self Not self](http://www.accesstoinsight.org/lib/authors/thanissaro/notself2.html)

My understanding to date is that it not-self is to detach from the 5 aggregates. So to use an example. If i express anger or sadness, i should look to detach or disassociate myself from such emotions. This may be through meditation or mindfulness. 

1. Is my understanding correct? If incorrect, please use lay person examples that will allow me to relate or understand.
2. Are meditation and mindfulness the only methods of actualization?
