Tikkun olam means repairing the world. In Judaism, it refers to the responsibility of Jews to make life fairer, more humane and more worth living. Be it in the form of social justice, environmental awareness or humanitarianism, everyone can do something on a small scale to help repair the world. The principle is closely connected to the Jewish commandments of tzedakah (charity) and chesed (altruism). For religious Jews, tikkun olam is a commandment, and for secular Jews, it is an expression of Jewish identity and tradition without a necessary link to religion. Nowadays, tikkun olam is an active element of Jewish ethics and a way to express commitment for a better future.
