For the Celtic people of ancient Ireland, the natural world was a continuous prayer. Each mountain held a soul; each river, a heart. This "eucharist of nature" was living evidence of a divine worldview to which each Celt, as part of the "Great Circle," belonged. Like the fierce and loving people who beheld it, this sacred vision vanished with the coming of Christianity in the 5th century. Or did it? On The Invisible World, scholar and poet John O'Donohue recovers Celtic spirituality's original mysteries, sharing practices and beliefs that enrich Ireland and its people to this day.For the Celts all life was sacred, O'Donohue begins. Yet they reserved their greatest reverence not for what they could see – but for what they could not. Around them they sensed an "invisible world" – the great unknown from which they came and the source of eternal wonder in their lives. Through prayer, O'Donohue teaches, we may enter directly into this secret immensity and escape the psychological prisons we create for ourselves. Alive with loving scholarship and interwoven with prayers and poetry in the Celtic tradition, The Invisible World is an invitation to find freedom from your negativity and return your soul to the grace that is waiting unseen around you at this very moment.
