Karl Rahner’s book, Prayers for a lifetime, captures some of his accessible, prayerful language. It is a small book and easy to read. Small, prayerful books such as this are the best way to access Rahner’s spirituality as his denser, more formal theological writings are virtually impenetrable. I particularly recommend Encounters with silence. Find out more about Karl Rahner here: https://www.ignatianspirituality.com/ignatian-voices/20th-century-ignatian-voices/karl-rahner-sj/
