A negative feeling such as anger flares up on its own. But, in its initial stage, it remains within a certain limit. And it crosses this limit only when anger is allowed to intensify. The law of nature regarding negative feelings is that it gets activated for only about 30 seconds, and if it is checked, it gets defused like a balloon. Therefore, if a person checks his anger, and does not allow it to escalate, the negative feeling will ebb away naturally, without there being any negative outcome.
