In an essay on the origin of civilization in traditional cultures, A.K. Coomaraswamy wrote that "the principle of justice is the same throughout: that each member of the community should perform the task for which he or she is fitted by nature." The two ideas, justice and vocation, are inseparable. It is by way of the principle and practice of vocation that sanctity and reverence enter into human economy. It was thus possible for traditional cultures to conceive that "to work is to pray."
