The last decade has seen striking growth in the popularity of alternative spiritual practices requiring neither doctrinal explanation nor institutional affiliation. This essay offers a brief account of such contemporary beliefs before asking what it is like to negotiate the tension between the assumptions of secularity and the impulses towards extra-ordinary forms of experience. Some of the richest accounts of modern spirituality come from the 1930s, and this paper examines some of the period’s profoundest poetic explorations of belief before considering T. S. Eliot’s analysis of the modern situation in the light of Christian revelation.
