As long as we are no bodhisattvas on the higher level, maculation has to be somewhere in the mind. It is important that it comes out - otherwise you cannot watch it.
- Use the anger as a spiritual car. Sit down and look at "Who is angry", "Where is he/she" - go away from looking at WHAT makes you angry in the outside. These things differ and they are always the same.
- While sitting in meditation look at the anger-arousing event: what happend outside? What happened inside? How could i behave better next time? How to judge the situation better next time?
In this way it is possible to train such a situation without being involved. Like dry swimming. So the mind will be trained and the next time it will not be something new.
- Change the sides: imagine you would like to critisize a teacher and he becomes angry.
This technic is called "Equalizing and Exchanging One's Attitudes about Self and Others" and is better discribed here:http://www.berzinarchives.com/web/en/ar ... tudes.html
