Anam Cara always accepts you as you truly are, holding you in beauty and light.
In order to appreciate this relationship, you must first recognize your own
inner light and beauty. This is not always easy to do. The Celts believed
that forming an Anam Cara friendship would help you to awaken your awareness
of your own nature and experience the joys of others.
According to John O'Donahue, an accomplished Irish poet, philosopher and Catholic priest, "...You are joined in an ancient and eternal union with humanity that cuts across all barriers of time, convention, philosophy and definition. When you are blessed with an anam cara, the Irish believe, you have arrived at that most sacred place: home."
