It includes, as chapters three and five, two reworked articles previously published in academic journals. As clearly defined by Sarbacker, the book’s goal is to develop a new methodological approach to the study of yoga and meditation in the con- text of Hinduism and Buddhism, i.e. one that tries to balance both psycho- logical and sociological standpoints in the study of religion. is approach —as one may expect given the title of the book—is developed through the paradigm of the ‘numinous’ and ‘cessative’ dimensions of yoga, which roughly corresponds to the ecstasis vs. enstasis dichotomy coined by Mircea Eliade. According to the author’s own words (p. ), ‘the numinous rep- resents the manner in which a practitioner of yoga embodies the world- surmounting power of divinity, while the cessative dimension emphasizes the attainment of freedom through separation from phenomenal existence’. e author finds this methodological orientation to be the key to ‘a signif- icantly more sophisticated understanding of the relationship of Classical Yoga and Buddhism’ (p. ). An attempt is made to link the ‘tension’—and not real ‘opposition’—existing between the qualities of numinous and ces- sative to that existing between the categories of sam¯ apatti and nirodha in the context of Classical Yoga, and of ´ samatha and vipa´ syan¯ a in the Buddhist Mah¯ ay¯ ana context. A fundamental point in Sarbacker’s analysis is the idea that sam¯ adhi is composed by both numinous and cessative aspects, against previous characterizations, such as that by Eliade, stressing the ‘enstatic’ element only. Sarbacker devotes a large part of the introduction—which I found en- gaging and thought-provoking—to contextualize the object of his research, i.e. meditation, taking into account the theoretical issues that have been object of debate in the field of Religious Studies since the pioneering work of Eliade. Starting from the characterization of contemporary attitudes towards meditation, the author declares his intention to overcome the polarization between empathetic and critical approaches to the study of religion through the development of an integrative and interdisciplinary approach, which would eventually make that discipline ‘act as a medium for social and cultural renewal’ (p. ). He then declares his study to be
