beings. They are encouraged to have a chaṛdī kalā, or optimistic – resilience, view of life. Sikh teachings also stress the concept of sharing—vaṇḍ chakkō—through the distribution of free food at Sikh gurdwaras (langar), giving charitable donations, and working for the good of the community and others (sēvā). Sikhs believe that no matter what race, sex, or religion one is, all are equal in God's eyes. Men and women are equal and share the same rights, and women can lead prayers. As with all Dharmic religions (Hinduism, Jainism, Buddhism, and Sikhism), ahimsa (avoidance of violence) is a central concept. Economic implications A report in June 2015 on the Global Peace Index highlighted that the impact of violence on the global economy reached US$14.3 trillion. The report also found that the economic cost of violence is 13.4% of world GDP, equal to the total economic output of Brazil, Canada, France, Germany, Spain, and the UK combined.
