"Spirituality must be distinguished from religion—because people of every faith, and of none, have had the same sorts of spiritual experiences. While these states of mind are usually interpreted through the lens of one or another religious doctrine, we know that this is a mistake. Nothing that a Christian, a Muslim, and a Hindu can experience—self-transcending love, ecstasy, bliss, inner light—constitutes evidence in support of their traditional beliefs, because their beliefs are logically incompatible with one another. A deeper principle must be at work."
