With the season of Advent, the coming of Christ is imminent, and following the contours of the season leads through a rich time of preparation for God-with-us in the Incarnation. R. S. Thomas, a poet of waiting and anticipation, can be a profound guide for this season. His spiritual and poetic trajectory of discovering the presence of God - divine 'frequencies' - even in apparent absence, can help lead us into an Advent landscape of surrender, open-hearted discovery, epiphany and encounter. This collection of 28 reflections on Thomas's poetry travels through the season, and follows one of the traditional patterns of themes explored in each Sunday of Advent: a Carmelite pattern of waiting, accepting, journeying and birthing.
