When you are angry with someone and you throw your anger on him, you are creating a chain reaction. Now he too will be angry. This may continue for lives and you will go on being enemies. How can you end it? There is only one possibility. You can end it only in meditation, nowhere else, because in meditation you are not angry with someone: you are simply angry.
This difference is basic. You are not angry with someone. You are simply angry and the anger is released into the cosmos. You are not hateful towards anyone. If hate comes, you are simply hateful and the hate is thrown out. In meditation, emotions are not addressed. They are unaddressed. They move into the cosmos, and the cosmos purifies everything.
It is just like a dirty river falling into the ocean: the ocean will purify it. Whenever your anger, your hate, your sexuality, moves into the cosmos, into the ocean - it purifies it. If a dirty river falls into another river, then the other river also becomes dirty. When you are angry with someone, you are throwing your dirt at him. Then he will also throw his at you and this will become a mutual dirtying process.
In meditation you are throwing yourself into the cosmos to be purified. All the energy that you throw is purified in the cosmos. The cosmos is so vast and so great an ocean, you cannot make it dirty. In meditation we are not related with persons. In meditation we are related directly to the cosmos.
