The purpose of this essay is to make a contribution to the study of religious pluralism in the south Asian diasporas. The essay compares the establishment of ritual traditions of the Tamil Hindus and the Tamil Roman Catholics in Norway. There are several parallel developments, and the essay identifies some of these similarities. It is argued that features sometimes assumed to be unique of the Hindu diaspora may not always be so, but may be common features of several of the religious traditions of south Asia in the diaspora. Attention to the plurality of religious traditions in the south Asian diasporas is therefore sometimes a better strategy than the study of each religious tradition in isolation.
