To Saint Teresa, Carmel owes its élan and its psychology. Carmelite psychology was always realistic. Under the reformer’s influence it became more so. In fact, her prudence and supernatural wisdom made her require that contemplative life—and mystical experience when this is added—be made more and more dependent on [Christian doctrine], the sacraments, obedience to the church and to superiors, the practice of virtues, fidelity to the Rule. Only in this way can sentimentalism, illuminism, and quietism in any form whatsoever be avoided.
