This paper was first delivered as the keynote address at the 'Transnational Punjabis in the 21st Century: Beginnings, Junctures and Responses' Conference held in May 2011 at the University of the Fraser Valley, Abbotsford, British Columbia, Canada. It argues that there are two dimensions to evolving Sikh diasporic identities that are firmly anchored in being at home whilst in motion. These two dimensions are rooted in culture and dharam. The ways in which Sikh culture travels and evolves is illustrative of post-colonial transformations and largely dependent on the host culture as well as the product of being part of either an 'old' or 'new' diaspora - that is, being a diaspora that has been forged in either the age of colonization or the age of globalization. While it remains to be seen how a Sikh diasporic identity will be shaped in the future, it is apparent that diasporic processes will be played out on a global stage as communications between Sikhs and others throughout the world are further revolutionized.
