Mysticism is mostly employed in the context of theistic religions because historically, mysticism aims at a unification with God. It must be clarified if the project of comparative mysticism that this book suggests can be properly carried out when including non-theistic religions. The chapter examines phenomena such as quietism, ekstasis, and contemplation. Further, the relationship between various mystical mental attitudes will be considered. Mysticism has often been related to an altered state of consciousness, which creates a parallel between Abrahamic and Dharmic practices. Though in Buddhism, ecstasy in the strict sense of the term is absent, the Buddhist contemplation leads down similar paths as ecstasy-based mysticism. It is not subjective but ecstatic. Mistakenly, satori has been classified as a mystical experience in the subjectivist sense that Zen Buddhism aims to avoid.
