How soon do we recover from emotions, hatred, anger, or whatever? I think you should not have as an ideal that you will not get angry, but if you need an ideal, the ideal should be how soon you recover from the anger.
There is a beautiful teaching in one of the Buddhist texts which gives three similes for three types of anger. The first type of anger is compared to letters written on stone which never change, never go away. The second type of anger is compared to letters written on sand. The third type of anger is compared to letters written on water. Isn’t that beautiful? That quickness: the anger is there and also it is already over.
It is silly, it is really foolish for us to hold on to anger and cause ourselves more suffering. I think this is compared to someone who is spitting in the wind, because when you spit in the wind it comes back on your own face.
