This book examines how ancient Zoroastrianism is practiced in the US diaspora and how it has evolved dynamically. As it developed in the patriarchal cultures of Iran and India, to move beyond the dominant male perspective, this book focuses on women. The lived religion approach demonstrates that Zoroastrianism in their everyday experiences is more than just a religion, but is a spiritual path, an ethnic tradition, and a cultural identity. Some women challenge old patterns, and Zoroastrianism in the diaspora turns out to be multifaceted and vibrant, despite the fear held by some community members that it may become extinct.Richly illustrated with the narratives of subsequent generations of Iranian and Parsi immigrants as well as photos, the book gives a taste of the diverse Zoroastrian life across the US. It not only broadens the picture of the ethnoreligious landscape in the country and expands interest in Zoroastrian studies, but also highlights the role of social practice theory in the study of religion, demonstrating how it may apply to qualitative field research, stimulating further discussion.
