Recent years have seen important studies of the Carmelite Rule (1206/14). In English the most significant works are the essays in Albert’s Way: The First North American Congress on the Carmelite Rule, ed. Michael Mulhall, Rome: Institutum Carmelitanum, 1989; and Kees Waaijman’s The Mystical Space of Carmel: A Commentary on the Carmelite Rule, (Fiery Arrow Collection 1), Louvain: Peeters, 1999, which explores the mystical dimension of the Rule as a guide to personal and communal transformation.
