The following essay is a close reading of Madeleine L'Engle's science fantasy novel, "A Wind in the Door", in which young Meg Murry travels first to outer space and then into her younger brother's ailing cells. The novel is a fine example of high fantasy (also known as heroic fantasy) wherein a humble protagonist is called to a quest to fight a cosmic battle between good and evil. The essay analyzes specific expressions of evil in the novel: impersonality, narcissism, despair and blind empiricism. Meg's quest demonstrates particular spiritual practices that promote spiritual maturation and the ability to overcome evil: "kything", Naming, deepening and holding. L'Engle portrays these practices in a fresh way that can help both children and adults incorporate them into their day-to-day lives. Moreover, there are links between kything and holding and the "metta" and "tonglen", two types of Buddhist meditation. L'Engle affirms children's innate relational consciousness and presents spiritual practices that are relational, non-sectarian, practical, and eminently hopeful. (Contains 12 notes.)
