 A fourth type of religious experience is harder to describe: it can’t be characterized accurately in sensory language, even analogically, yet the subject of the experience insists that the experience is a real, direct awareness of some religiously significant reality external to the subject. These kinds of experiences are usually described as “ineffable.” Depending on one’s purposes, other ways of dividing up religious experiences will suggest themselves. For example, William James (1902) divides experiences into “healthy-minded” and “sick-minded,” according to the personality of the subject, which colors the content of the experience itself. Keith Yandell (1993, 25–32) divided them into five categories, according to the content of the experiences: monotheistic, nirvanic (enlightenment experiences associated with Buddhism), kevalic (enlightenment experiences associated with Jainism), moksha (experiences of release from karma, associated with Hinduism), and nature experiences. Differences of object certainly make differences in content, and so make differences in what can be said about the experiences. See Section 4 for further discussion of this issue.
