Akrodha is demonstrated when there is a reason why someone might become angry, but they do not succumb to anger. It is not the absence of causes of anger, but the absence of an angry reaction to these potential causes. This means that the person remains calm in the face of provocation, insults, or abuse.
The opposite of akrodha - krodha or "anger" - is excessive mental agitation when some desire or attachment is not fulfilled. In this state, anger clouds judgement and peace of mind. In contrast, when the state of akrodha is achieved, a person’s mind is clear and free, and they are able to find self-knowledge, truth and liberation. They will also not harm others through their anger.
