The common core thesis contends that mystical experience is an ultimate non-sensuous experience of unity of all things. It can be identified within major faith traditions, whether explicitly religious or not. Its roots are in the work of William James who explored mystical experience outside the limits imposed by what he perceived as only a provisional natural science assumption of the newly emerging discipline of empirical psychology. Following the explicit phenomenological work of Walter Stace, the phenomenology of a universal core to mystical experience has been operationalized and an explicit psychometric measure developed to allow empirical assessment of the claim to a common core to mysticism. It is the linkage of psychometric approaches to the work of James and Stace that is now known explicitly as the common core thesis. The common core thesis needs to be delineated from the perennialist thesis popularized by Aldous Huxley in which there is postulated not only a common core experience, but also values and practices claimed to be associated with this experience if not directly derived from it. Psychometric and empirical evidence for the common core thesis is substantial and continues to accumulate. The common core thesis is restricted to mystical experience and assumes that this experience seeks to express itself in various faith traditions, whether religious or not, but is not restricted to or defined adequately by the culture or language with which this experience is interpreted. Unlike the perennialist thesis, the common core thesis does not assume that any common theology, philosophy, or practice necessarily follows from mystical experience.
The comparative study of mysticism began in the mid-19th century, with the development of the modern meaning of the word, which had begun to be used as a substantive, with the classification of “mystics” in the 17th century. This differed from the traditional Greek Christian use of the adjective mystikos, to qualify rituals, scriptures, sacraments, and theology as “mystical” contexts of the human encounter with the Divine. This modern shift highlighted the personal experience of ultimate Reality, rather than the sociocultural context. Certain individuals claimed to encounter the Divine or spiritual realities more directly, separate from traditional mediums of religious experience. The study of this phenomenon tended in the early 20th century to focus on the psychology and the phenomenology of the personal experience, generally described as an altered state of consciousness with specific characteristics, processes, stages, effects, and stimulants. This emphasis on common features influenced the development of perennialist and traditionalist theorists, who saw evidence of the same experiential origin, fundamental principles, or epistemology among major world religions. Some essentialist views of mysticism argued that a pure consciousness-experience of undifferentiated unity or non-duality is the core feature of all mysticism, in contrast to other religious experiences. Reaction to these positions led to contextualist or constructivist views of mysticism, which presume the sociocultural character of mysticism. In its most extreme form, the contextualist perspective suggests that all mystical experiences among traditions are different, given diverse socio-religious categories that overdetermine the experience. In turn, some critical scholarship has proposed qualifications to contextualism within the context of a general acceptance of many of its tenets, even among many theorists with essentialist tendencies.
Up to the late 20th century, much scholarship in the area tended to downplay the sociocultural features of mysticism, emphasizing the psychological dynamics and an individual, disembodied, and radically transcendent ideal. This brought into question the relationship of morality to mystical experience and raised concerns about the status of entheogens—the use of psychoactive drugs in religious contexts. Interest in the comparative study of mysticism has also extended into the area of neuroscience, where researchers explore electro-chemical brain states associated with mystical experience, in proposing evidence of a mystical neurological substrate. But the essentialist/contextualist debate also moved the comparative study of mysticism beyond issues of epistemology, consciousness-states, ontology, and cognitive neuroscience, broadening the field to include other aspects of religious experience. Some studies have brought feminist concerns to bear on the discussion, insofar as women’s mysticism has been overshadowed and even repressed by men, and was seen to preclude legitimate experiential possibilities of a more embodied character. Related scholarship in history and depth psychology has focused creatively on the nature and significance of erotic elements of mysticism in comparative studies, with special attention to associated physical phenomena and their transformative dynamics. Similarly, more embodied features of comparative mysticism are the subject of transpersonal psychology, which draws on many humanistic disciplines and supports participatory approaches to the field. Transpersonal psychology remains open to claims that the ego can be transcended in movements into higher states of being that ideally involve personal/spiritual enhancement and integration. Also, some more recent proponents of new comparative theology advocate methods that engage the scholar in specific beliefs or practices of another tradition, and include subsequent clarification and elaboration of one’s own perspective in light of such comparative study, in exploring phenomena related to comparative mystical experience.

Erotic representations of the divine occupy a pivotal place in religious myths, poetry, liturgy, and theology. Reading eros as a category of religious love highlights its ubiquitous presence in sacred literary sources; moreover, it renders the nexus of erotic love and the divine critical to comprehending religiosity as an immanent and embodied phenomenon, rather than as an abstract idea. As an embodied phenomenon, religious love is subject to an investigation of topics such as gender and sexuality, and its multiple cultural meanings and contexts. Western philosophers such as Plato, Aristotle, (Pseudo-)Dionysius, and the Neoplatonist renaissance thinker Leone Ebreo, delineate a hierarchy or a “ladder of love” differentiating lesser and higher subjects and objects of love from love of the particular, to the universal, cosmic, and divine. An interrelated distinction is ascertained between “desire” as a state of lack often seen as a lower state, and “love” as the higher state, in which fulfillment and joy of the union with the object of one’s love is achieved. Love and desire as marked yet interrelated emotions are contextualized in religious phenomena cross-culturally, most obviously in theistic frameworks in which a personal and intimate relationship with the divine is an ideal. Poetry and autobiography are the most common genre of depicting the intimate and passionate encounter of human and divine. Despite the prominence of male voices in the sources, the contributions of medieval Christian and Muslim women mystics to this literature are significant. Key base-texts from which mystics and philosophers are inspired and draw upon to elucidate their own personal experience of yearning for the divine, include the biblical Song of Songs, Bhagavata Purana (Book 10), and the Gitagovinda. Although the yearning for the divine, associated with an emotional, embodied state and therefore seen as problematic from a rational perspective, this yearning is also a cherished state, even for rationalists such as the medieval Jewish thinker Moses Maimonides. The significance of erotic love for the divine is confirmed, not only by Sufi and Hindu bhakti poets such as Rumi and Jayadeva, but also by philosophers such as Ibn Arabi and Rupa-Goswami. The idiom of erotic desire and love for God is particularly poignant and integral not only in poetry but also in theology, as exemplified in Hindu bhakti and Christian theology. Exploring the meanings of erotic love in religious poetry, theology, liturgy, and the history of religion more broadly offers a rich scholarly and personal medium for contemplating the reality of human and divine nature.
