This chapter outlines Sikh religion's history, beliefs, and symbols; and discusses the religion's contribution to positive functioning and well-being for the Sikh community. In particular, Sikhism's emphasis on interdependence, community service, and social justice are viewed through the positive psychology framework as described by Dahlsgaard, Peterson, and Seligman (Rev Gen Psychol 9(3):203–213, 2005), with reference to Seligman and Csikszentimihalyi (Am Psychol 55:5–14, 2000). A discussion is provided on how Sikhs have capitalized on strengths to lead more satisfying and meaningful lives in the face of discrimination and hate crimes. For psychologists, this information is helpful in understanding how religion can be an important source of strength and resilience for individuals, families, and communities in the face of current challenges.
