The last words of Birchas Kohanim are "V'Yaseim Licha Sholom". The Medrash says, "Sholom B'Knisasech, Sholom B'Yitziasech, Sholom Im Kol Adam," peace in your coming, your going, and peace with every man.
The Iturei Torah brings the Ksav Sofer who explains this Medrash. The Gemara in Brachos (59) tells us the interpretation of many different dreams. Among these dreams, three of them tell of peace; the kettle, the river, and the bird. The Ksav Sofer says that these represent three different kinds of peace. The kettle represents peace in your home, where all the household members use the same kettle. The river means peace in your country, where all the citizens share the water and benefits of the country's river. The bird symbolizes world peace, like a bird who is not limited to any specific local and can fly wherever its wings take it.
When Hashem gives us a bracha of peace it is all encompassing. The Medrash says, "Sholom B'Knisasech," you will have peace in your coming, meaning within the confines of your home. "Sholom B'Yitziasech," peace when you go outside and interact with your countrymen. "Sholom Im Kol Adam," no matter where and no matter with whom, peace will reign supreme!
