when we hold on to a particular belief

 We are very defensive, and therefore aggressive, when we hold on to a particular belief, a dogmas, or when we worship our particular nationality, with the rag that is called the flag.
― Jiddu Krishnamurti, What are You Doing with Your Life: Teen Books on Living Volume 1

Identification with the rag called the national flag is an emotional and sentimental factor and for that factor you are willing to kill another - and that is called, the love of your country, love of the neighbor . . .? One can see that where sentiment and emotion come in, love is not.
