A large portion of Possamai's published work is premised on a neo-Weberian approach to the sociology of religion and popular culture. His contributions to the study of religion and popular culture are being acclaimed as significant works. In exploring the manner in which the internet has become a source of religious inspiration, Possamai has discussed the emergence of what he dubs "hyper-real religions". This is an entirely new theoretical framework for conceptualising consumerism in religion in the context of globalization. He detects a synergy between various stories and icons of popular culture and the role of the individual to create a new religious message. Possamai explores the intersection between late modernity and spirituality, noting the emphasis on the authority of the self replacing external forms of conventional religious authority. Hyper-real religions constitute new forms of spirituality where traditional and modern religious ideas are consumed and projected into completely forms. Examples cited by Possamai include the Church of All Worlds, the Church of Satan, and Jedi religion. Carole Cusack in her book Invented Religions: Imagination, Fiction and Faith stated that "Adam Possamai,... to date is the only sociologist of religion to examine it in any detail prior to this study". His work also considers the complex interplay between fundamentalistChristian groups that resist the synergy between popular culture and religion, and yet reappropriate aspects of pop culture to promote fundamentalism. The second area of scholarly innovation is found in Possamai's work on New Age spirituality. On the basis of both field research in alternative spirituality festivals and new theoretical approaches, Possamai has contested the scholarly status quo in the interpretation and classification of New Age spirituality. His field research demonstrates that very few practitioners of what scholars call New Age, actually accept the term. He argues that the term New Age is imprecise and the previous scholarly conceptualisations of New Age are either limited or misleading. In his new schema, New Age spirituality is but one facet of a much wider cultural phenomenon that he has dubbed a perennist spirituality. It follows that by culturally consuming selected practices, myths, and teachings from pre-modern times, and then reframing them for the contemporary scene, seekers aspire to personal transformation and perhaps resolving global woes. At the heart of this conceptualisation of reality lies a commitment to what Possamai has dubbed "perennism", the notion that a holistic understanding of truth is accessible in esoteric wisdom or gnosis that is unfettered by the dogmas of the world's religions. According to Possamai, the key features of perennism are that in this syncretic spirituality the cosmos is interpreted as a monistic reality, which partakes of a single unifying being, or principle, and all parts of the cosmos are inter-related to this ultimate reality. Those who participate in this spirituality are engaged in self-development to attain their potential, and they pursue spiritual knowledge of both self and ultimate reality.
