This is really a "how to" book - how to bring Celtic Spirituality into your own life. Donald lives in Scotland and the book is full of his personal experiences as he visits sacred sites through out Britain and Ireland. I found it totally inspiring. It takes you through each step of understanding what the Celts believed and then how to apply it to your own life. He looks at working with sacred sites, meditations, pilgrimages. He shows you how to work with trees, crystals, natural elements. He reveals how to celebrate the rhythms of the year. And in an amazing third section he shows you how to apply these lessons to every aspect of your life.
It has transformed my life. Check out his website. Loads of info and his newsletters are awesome.
