This is your weakness; so, you must spend time watching anger. You need to spend a lot of time looking at what you think is noise, learning about your mind’s reaction to it.
Every time you have a reaction to the noise, you should watch the anger. Watch it until it’s gone and then look at the noise. You must do this.
It is only when the mind has no reaction to the noise that the mind has learnt its lesson. If it has a reaction, it is something we must learn from.
