Book excerpt: The Meditations, written over a period from 1125 to 1137, are a personal account of William of Saint-Thierry’s ascent into Trinitarian intimacy. Writing to the monks of Mont Dieu sometime around 1144, he proposed the Meditations as helpful in forming minds in prayer. These Meditations, with their accompanying commentary, are now presented as helpful in forming an intimate relationship with the triune God.
